Mozilla has taken a notable step toward improving Firefox distribution on Linux. An official Firefox RPM package is now available directly from Mozilla for Fedora-style distributions, including Fedora, RHEL-compatible systems, and related derivatives. This move gives users a new, upstream-supported option for installing and maintaining Firefox without relying solely on distro-maintained builds.

What’s Changed

Until now, users on RPM-based systems typically installed Firefox through their distribution’s repositories. While those packages are usually well-maintained, they can sometimes lag behind Mozilla’s release schedule or include distro-specific patches.

With the new official RPM, Mozilla provides:

• A Firefox build maintained directly by Mozilla

• Faster access to new releases and security updates

• A consistent Firefox experience across RPM-based distros

• Reduced dependency on downstream packaging delays

This mirrors the approach Mozilla already uses for official DEB packages and tarball releases, bringing parity to RPM-based ecosystems.

Who Benefits Most

This new packaging option is especially useful for:

• Fedora users who want Firefox updates the moment Mozilla releases them

• Developers and testers who need predictable, upstream Firefox behavior

• Enterprise or workstation users running Fedora-derived systems who prefer vendor-supplied binaries

• Users who want to avoid Flatpak or Snap for their browser

Distributions that prioritize stability over immediacy may still ship older versions, but the official RPM gives users a clear choice.

How It Works

Mozilla hosts a signed RPM repository that integrates cleanly with dnf-based systems. Once added, Firefox updates arrive through the standard system update process, just like any other RPM package.

Key characteristics include:

• GPG-signed packages from Mozilla

• Automatic updates via dnf upgrade

• No repackaging or third-party rebuilds

• Compatibility with Fedora and compatible RPM distros

Users can choose between the distro-provided Firefox or Mozilla’s upstream RPM without conflict, as long as only one source is enabled.

Why This Matters for Linux Users

This change reflects a broader trend: upstream projects taking more responsibility for how their software reaches users. For Firefox, that means:

One of the most widely deployed Linux kernels has officially reached the end of its lifecycle. The maintainers of the Linux kernel have confirmed that Linux 5.4, once a cornerstone of countless servers, desktops, and embedded devices, is now end-of-life (EOL). After years of long-term support, the branch has been retired and will no longer receive upstream fixes or security updates.

A Kernel Release That Defined a Generation of Linux Systems

When Linux 5.4 debuted, it made headlines for bringing native exFAT support, broader hardware compatibility, and performance improvements that many distributions quickly embraced. It became the foundation for major OS releases, including Ubuntu LTS, certain ChromeOS versions, Android kernels, and numerous appliance and IoT devices.

Its long support window made it a favorite for organizations seeking stability over bleeding-edge features.

What End-of-Life Actually Means

With the EOL announcement, the upstream kernel maintainers are officially done with version 5.4. That means:

• No more security patches

• No more bug fixes or performance updates

• No regressions or vulnerabilities will be addressed

Some enterprise vendors may continue backporting patches privately, but the public upstream branch is now frozen. For most users, that makes 5.4 effectively unsafe to run.

Why This Matters for Users and Organizations

Many devices, especially embedded systems, tend to run kernels for much longer than desktops or servers. If those systems continue using 5.4, they now risk exposure to unpatched vulnerabilities.

Running an unsupported kernel can also create compliance issues for companies operating under strict security guidelines or certifications. Even home users running older LTS distributions may unknowingly remain on a kernel that’s no longer protected.

Upgrading Is the Clear Next Step

With 5.4 retired, users should begin planning an upgrade to a supported kernel line. Today’s active long-term support kernels include more modern branches such as 6.1, 6.6, and 6.8, which provide:

• Better CPU and GPU support

• Significant security improvements

• Enhanced performance and energy efficiency

• Longer future support windows

Before upgrading, organizations should test workloads, custom drivers, and hardware, especially with specialized or embedded deployments.

For years, Windows users frustrated with constant changes, aggressive updates, and growing system bloat have flirted with switching to Linux. But 2025 marks a noticeable shift: a new generation of Linux distributions built specifically for ex-Windows users is gaining real traction. One of the standout examples is Bazzite, a gaming-optimized Fedora-based distro that has quickly become a go-to choice for people abandoning Windows in favor of a cleaner, more customizable experience.

Why Many Windows Users Are Finally Jumping Ship

Microsoft’s ecosystem has been slowly pushing some users toward the exit. Hardware requirements for Windows 11 left millions of perfectly functional PCs behind. Ads on the Start menu and in system notifications have frustrated many. And for gamers, launcher problems, forced reboots and background processes that siphon resources have driven a search for alternatives.

Linux distributions have benefited from that frustration, especially those that focus on simplicity, performance and gaming readiness.

Gaming-First Distros Are Leading the Movement

Historically, switching to Linux meant sacrificing game compatibility. But with Valve’s Proton layer and Vulkan-based translation technologies, thousands of Windows games now run flawlessly, sometimes better than on Windows.

Distros targeting former Windows users are leaning into this new reality:

• Seamless Steam integration

• Automatic driver configuration for AMD, Intel and NVIDIA

• Built-in performance overlays like MangoHUD

• Proton GE and tools for modding or shader fixes

• Support for HDR, VR and modern controller layouts

This means a new Linux user can install one of these distros and jump straight into gaming with almost no setup.

Bazzite: A Standout Alternative OS

Bazzite has become the poster child for this trend. Built on Fedora’s image-based system and the Universal Blue infrastructure, it offers an incredibly stable base that updates atomically, similar to SteamOS.

What makes Bazzite so attractive to Windows refugees?

• Gaming-ready out of the box no tweaking, no driver hunts

• Rock-solid performance thanks to an immutable system layout

• Support for handheld PCs like the Steam Deck, ROG Ally and Legion Go

• Friendly workflows that feel familiar to new Linux users

• Customization without the risk of breaking the system

It’s no surprise that many “I switched to Linux!” posts now mention Bazzite as their distro of choice.

The stable release of Linux Kernel 6.18 was officially tagged on November 30, 2025.

It’s expected to become this year’s major long-term support (LTS) kernel, something many users and distributions care about.

Here’s a breakdown of the most significant changes and improvements in this release:

Core Improvements: Performance, Memory, Infrastructure

• The kernel’s memory allocation subsystem gets a major upgrade with “sheaves”, a per-CPU caching layer for slab allocations. This reduces locking overhead and speeds up memory allocation and freeing, improving overall system responsiveness.

• A new device-mapper target dm-pcache arrives, enabling use of persistent memory (e.g. NVDIMM/CXL) as a cache layer for block devices, useful for systems with fast non-volatile memory, SSDs, or hybrid storage.

• Overall memory management and swapping performance have been improved, which should help under memory pressure or heavy workloads.

Networking & Security Enhancements

• Networking gets a boost: support for Accurate Explicit Congestion Notification (AccECN) in TCP, which can provide better congestion signals and more efficient network behaviour under load.

• A new option for PSP-encrypted TCP connections has been added, a fresh attempt to push more secure transport-layer encryption (like a more efficient alternative to IPsec/TLS for some workloads) under kernel control.

• The kernel now supports cryptographically signed BPF programs (eBPF), so BPF bytecode loaded at runtime can be verified for integrity. This is a noteworthy security hardening step.

• The overall security infrastructure and auditing path, including multi-LSM (Linux Security Modules) support, has been refined, improving compatibility for setups using SELinux, AppArmor, or similar simultaneously.

Hardware, Drivers & Architecture Coverage

• Kernel 6.18 brings enhanced hardware support: updated and new drivers for many platforms across architectures (x86_64, ARM, RISC-V, MIPS, etc.), including improvements for GPUs, CPU power management, storage controllers, and more.

• In particular, support for newer SoCs, chipsets, and embedded-board device trees has been extended, beneficial for people using SBCs, ARM-based laptops/boards, or niche hardware.

• For gaming rigs, laptops, and desktops alike: improvements to drivers, power-state management, and performance tuning may lead to better overall hardware efficiency.

If you use Linux and occasionally run Windows applications, whether via native Wine or through gaming layers like Proton, you’ll appreciate what just dropped in Wine 10.19. Released November 14 2025, this version brings a major enhancement: official support for Windows reparse points, a filesystem feature many Windows apps rely on, and a host of other compatibility upgrades.

In simpler terms: Wine now understands more of the Windows filesystem semantics, which means fewer workarounds, better application compatibility, and smoother experiences for many games and tools previously finicky under Linux.

What Are Reparse Points & Why They Matter Understanding Reparse Points

On Windows, a reparse point is a filesystem object (file or directory) that carries additional data, often used for symbolic links, junctions, mount points, or other redirection features. When an application opens or queries a file, the OS may check the reparse tag to determine special behavior (for example “redirect this file open to this other path”).

Because many Windows apps, installers, games, DRM systems, file-managers, use reparse points for features like directory redirection, path abstractions, or filesystem overlays, lacking full support for them in Wine means those apps often misbehave.

What Wine 10.19 Adds

With Wine 10.19, support for these reparse point mechanisms has been implemented in key filesystem APIs: for example NtQueryDirectoryFile, GetFileInfo, file attribute tags, and DeleteFile/RemoveDirectory for reparse objects.

This means that in Wine 10.19:

• Windows apps that create or manage symbolic links, directory junctions or mount-point style re-parsing will now function correctly in many more cases.

• Installers or frameworks that rely on “when opening path X, redirect to path Y” will work with less tinkering.

• Games or utilities that check for reparse tags or use directory redirections will have fewer “stuck” behaviors or missing files.

In effect, this is a step toward closer to native behavior for Windows file-system semantics under Linux.

Other Key Highlights in Wine 10.19

Beyond reparse points, the release brings several notable improvements:

• Expanded support for WinRT exceptions (Windows Runtime error handling) meaning better compatibility for Universal Windows Platform (UWP) apps and newer Windows-based frameworks.

• Refactoring of “Common Controls” (COMCTL32) following the version 5 vs version 6 split, which helps GUI applications that rely on older controls or expect mixed versions.

Mozilla has rolled out Firefox 145, a significant update that brings a range of usability, security and privacy enhancements, while marking a clear turning point by discontinuing official support for 32-bit Linux systems. For users on older hardware or legacy distros, this change means it’s time to consider moving to a 64-bit environment or opting for a supported version.

Here’s a detailed look at what’s new, what’s changed, and what you need to know.

Major Changes in Firefox 145 End of 32-Bit Linux Builds

One of the headline items in this release is Mozilla’s decision to stop building and distributing Firefox for 32-bit x86 Linux. As per their announcement:

“32-bit Linux (on x86) is no longer widely supported by the vast majority of Linux distributions, and maintaining Firefox on this platform has become increasingly difficult and unreliable.”

From Firefox 145 onward, only 64-bit (x86_64) and relevant 64-bit architectures (such as ARM64) will be officially supported. For those still running 32-bit Linux builds, Mozilla recommends migrating to 64-bit or switching to the Extended Support Release (ESR) branch (Firefox 140 ESR) which still supports 32-bit for a limited period.

Usability & Interface Enhancements

Firefox 145 brings several improvements designed to make everyday web browsing smoother and more flexible:

• PDF viewer enhancements: You can now add, edit, and delete comments in PDFs, and a comments sidebar helps you easily navigate your annotations.

• Tab-group preview: When you hover over the name of a collapsed tab group, a thumbnail preview of the tabs inside appears, helpful for reorganizing or returning to work.

• Access saved passwords from the sidebar, without needing to open a new tab or window.

• “Open links from apps next to your active tab” setting: When enabled, links opened from external applications insert next to your current tab instead of at the end of the tab bar.

• Slight UI refinements: Buttons, input fields, tabs and other elements get more rounded edges, horizontal tabs are redesigned to align with vertical-tab aesthetics.

Privacy, Security & Under-the-Hood Upgrades

Mozilla has also doubled down on privacy and risk reduction:

• Fingerprinting defenses: Firefox 145 introduces new anti-fingerprinting techniques that Mozilla estimates reduce the number of users identified as unique by nearly half when Private Browsing mode or Enhanced Tracking Protection (strict) is used.

The team behind MX Linux has just released version 25, carrying the codename “Infinity”, and it brings a significant upgrade by building upon the stable base of Debian 13 “Trixie”. Released on November 9, 2025, this edition doesn’t just refresh the desktop, it introduces modernized tooling, updated kernels, dual init-options, and installer enhancements aimed at both newcomers and long-time users.

In the sections that follow, we’ll walk through the key new features of MX Linux 25, what’s changed for each desktop edition, recommended upgrade or fresh-install paths, and why this release matters in the wider Linux-distribution ecosystem.

What’s New in MX Linux 25 “Infinity”

Here are the headline changes and improvements that define this release:

Debian 13 “Trixie” Base

By moving to Debian 13, Infinity inherits all the stability, security updates, and broader hardware support of the latest Debian stable release. The base system now aligns with Trixie’s libraries, kernels, and architecture support.

Kernel Choices & Hardware Support

• The standard editions ship with the Linux 6.12 LTS kernel series, offering a solid baseline for most hardware.

• For newer hardware or advanced users, the “AHS” (Advanced Hardware Support) variants and the KDE Plasma edition adopt a Liquorix-flavored Linux 6.16 (or 6.15 in some variants) kernel, maximizing performance and compatibility with cutting-edge setups.

Dual Init Option: systemd and SysVinit

Traditionally associated with lighter-weight init options, MX Linux now offers both systemd by default and SysVinit editions (particularly for Xfce and Fluxbox variants). This gives users the freedom to choose their init system preference without losing new features.

Updated Desktop Environments

• Xfce edition: Ships with Xfce 4.20. Improvements include a revamped Whisker Menu, updated archive management tools (Engrampa replacing File Roller in some editions).

• KDE Plasma edition: Uses KDE Plasma 6.3.6, defaults to Wayland for a modern session experience (with X11 still optionally available), adds root-actions and service menus to Dolphin, and switches TLP out for power-profiles-daemon to resolve power widget issues.

• Fluxbox edition: Offers a more minimal, highly customizable environment: new panel layouts, updated “appfinder” configs for Rofi, toolbar changes and themes refined. Defaults the audio player to Audacious (instead of the older DeaDBeeF).

Arch Linux has shipped its November 2025 ISO snapshot (2025.11.01), and while Arch remains a rolling distribution, these monthly images are a big deal, especially for new installs, labs, and homelab deployments. This time, the ISO lands alongside two important pieces:

• Archinstall 3.0.12 – a more polished, smarter TUI installer

• Pacman 7.1 – a package manager update with stricter security and better tooling

If you’ve been thinking about spinning up a fresh Arch box, or you’re curious what changed under the hood, this release is a very nice jumping-on point.

Why Arch Still Ships Monthly ISOs in a Rolling World

Arch is famous for its “install once, update forever” model. Technically, you could install from a two-year-old image and just run:

sudo pacman -Syu

…but in practice, that’s painful:

• Huge initial update downloads

• Possible breakage jumping across many months of changes

• Outdated installer tooling

That’s why the project publishes a monthly snapshot ISO: it rolls all current packages into a fresh image so you:

• Start with a current kernel and userland

• Spend less time updating right after install

• Get the latest Archinstall baked in (or just a pacman -Sy archinstall away)

The 2025.11.01 ISO is exactly that: Arch as of early November 2025, ready to go.

What’s Inside the November 2025 ISO (2025.11.01)

The November snapshot doesn’t introduce new features by itself, it’s a frozen image of current Arch, but a few details are worth calling out:

• Ships with a Linux 6.17.x kernel, including improved AMD/Intel GPU support and updated Btrfs bits.

• Includes all the usual base packages plus current toolchains, drivers, and desktop stacks from the rolling repos.

• The image is intended only for new installs; existing Arch systems should keep using pacman -Syu for upgrades.

You can download it from the official Arch Linux download page or via BitTorrent mirrors.

One small twist: the ISO itself still ships with Archinstall 3.0.11, but 3.0.12 was released the same day – so we’ll grab the newer version from the repos before running the installer.

Archinstall 3.0.12: What’s Actually New?

Archinstall has evolved from “nice experiment” to “pretty solid way to install Arch” if you don’t want to script everything yourself. Version 3.0.12 is a refinement release focused on stability, storage, and bootloader logic.

AMD has officially confirmed a high-severity security vulnerability in its new Zen 5–based CPUs, and it’s a nasty one because it hits cryptography right at the source: the hardware random number generator.

Here’s a clear breakdown of what’s going on, how bad it really is, and what you should do if you’re running Zen 5.

What AMD Just Confirmed

AMD’s security bulletin AMD-SB-7055, now tracked as CVE-2025-62626, describes a bug in the RDSEED instruction on Zen 5 processors. Under certain conditions, the CPU can:

• Return the value 0 from RDSEED far more often than true randomness would allow

• Still signal “success” (carry flag CF=1), so software thinks it got a good random value

The issue affects the 16-bit and 32-bit forms of RDSEED on Zen 5; the 64-bit form is not affected.

Because RDSEED is used to feed cryptographically secure random number generators (CSPRNGs), a broken RDSEED can poison keys, tokens, and other security-critical values.

AMD classifies the impact as:

Loss of confidentiality and integrity (High severity).

How the Vulnerability Works (In Plain English) What RDSEED Is Supposed to Do

Modern CPUs expose hardware instructions like RDRAND and RDSEED:

• RDRAND: Gives you pseudo-random values from a DRBG that’s already been seeded.

• RDSEED: Gives you raw entropy samples suitable for seeding cryptographic PRNGs (it should be very close to truly random).

Software like TLS libraries, key generators, HSM emulators, and OS RNGs may rely directly or indirectly on RDSEED to bootstrap secure randomness.

What’s Going Wrong on Zen 5

On affected Zen 5 CPUs:

• The 16-bit and 32-bit RDSEED variants sometimes return 0 much more often than a true random source should.

• Even worse, they simultaneously report success (CF=1), so software assumes the value is fine rather than retrying.

In cryptographic terms, this means:

• Entropy can be dramatically reduced (many key bits become predictable or even fixed).

• Keys or nonces derived from those values can become partially or fully guessable.

The Linux kernel, foundational for servers, desktops, embedded systems, and cloud infrastructure, has been under heightened scrutiny. Several vulnerabilities have been exploited in real-world attacks, targeting critical subsystems and isolation layers. In this article, we’ll walk through major examples, explain their significance, and offer actionable guidance for defenders.

CVE-2025-21756 – Use-After-Free in the vsock Subsystem

One of the most alarming flaws this year involves a use-after-free vulnerability in the Linux kernel’s vsock implementation (Virtual Socket), which enables communication between virtual machines and their hosts.

How the exploit works: A malicious actor inside a VM (or other privileged context) manipulates reference counters when a vsock transport is reassigned. The code ends up freeing a socket object while it’s still in use, enabling memory corruption and potentially root-level access.

Why it matters: Since vsock is used for VM-to-host and inter-VM communication, this flaw breaks a key isolation barrier. In multi-tenant cloud environments or container hosts that expose vsock endpoints, the impact can be severe.

Mitigation: Kernel maintainers have released patches. If your systems run hosts, hypervisors, or other environments where vsock is present, make sure the kernel is updated and virtualization subsystems are patched.

CVE-2025-38236 – Out-of-Bounds / Sandbox Escape via UNIX Domain Sockets

Another high-impact vulnerability involves the UNIX domain socket interface and the MSG_OOB flag. The bug was publicly detailed in August 2025 and is already in active discussion.

Attack scenario: A process running inside a sandbox (for example a browser renderer) can exploit MSG_OOB operations on a UNIX domain socket to trigger a use-after-free or out-of-bounds read/write. That allows leaking kernel pointers or memory and then chaining to full kernel privilege escalation.

Why it matters: This vulnerability is especially dangerous because it bridges from a low-privilege sandboxed process to kernel-level compromise. Many systems assume sandboxed code is safe; this attack undermines that assumption.

Mitigation: Distributions and vendors (like browser teams) have disabled or restricted MSG_OOB usage for sandboxed contexts. Kernel patches are available. Systems that run browser sandboxes or other sandboxed processes need to apply these updates immediately.

CVE-2025-38352 – TOCTOU Race Condition in POSIX CPU Timers

In September 2025, the U.S. Cybersecurity & Infrastructure Security Agency (CISA) added this vulnerability to its Known Exploited Vulnerabilities (KEV) catalog.
