Linux 7.1 is now publicly available, ending support for i486 processors. The release fixes Steam Deck audio and overhauls NTFS. Linus Torvalds announced the release early Sunday from a different time zone due to travel, with the 7.2 merge window timing also affected.
Zinnia is a modular 64-bit Unix-like kernel written in nearly 100% Rust, avoiding unsafe code where possible. It implements POSIX APIs plus Linux and BSD extensions like epoll and timerfd, enabling modern desktop sessions via Wayland and X11. Drivers load as Rust ELF dylibs from an initrd, booting on any UEFI x86_64 system.
The Linux 7.1 kernel version was released featuring improved power management and enhanced security protocols. It includes support for new hardware drivers and optimized performance on mobile devices. The update is available for all major distributions including Ubuntu and Fedora.
Linux 7.1 introduces the FRED framework, a new NTFS driver, and additional performance improvements. The FRED feature provides a more flexible execution environment for kernel developers. The updated NTFS driver offers better support for Windows filesystems. These changes aim to enhance system responsiveness and hardware compatibility.

MIT researchers built the Fractal kernel to expose processor internals. It uncovered previously unknown behavior in Apple's M1 chip and a possible Phantom attack. The kernel gives security researchers a clearer view of hardware operations.

A logic inversion bug in the Linux kernel (CVE-2026-23111) allowed local privilege escalation. Discovered by Oliver Sieber from Exodus Intelligence, the flaw affected Debian, Ubuntu, and RHEL 10. Fixes are rolling out unevenly, with Ubuntu and Debian patched but Red Hat, SUSE, and Amazon Linux still exposed.

A high-severity Linux vulnerability, CVE-2026-23111, in the nf_tables kernel subsystem allows unprivileged users to escalate to root. A single misplaced exclamation point in the code introduced a use-after-free bug. Researchers from Exodus Intelligence demonstrated the exploit on Debian and Ubuntu systems.
AMD support is being added to the UFS host controller PCI driver in Linux 7.2. The patch enables AMD platforms to use the Universal Flash Storage host controller over PCI. This integration expands storage driver compatibility for AMD hardware within the Linux kernel.

A single-character flaw in the Linux kernel's nf_tables code, CVE-2026-23111, lets unprivileged users escalate to root and escape containers. Patched upstream on February 5, 2026, public exploits from Exodus Intelligence and FuzzingLabs are now available. Ubuntu rates it CVSS 7.8. Update and reboot if unpatched.
A developer volunteered to maintain the Linux kernel's old, rare EFS file-system driver but admitted to not using it and only submitted basic fixes. The Linux kernel mailing list now debates whether to keep the unmaintained code or remove it entirely.
