Linux 6.15 est officiellement disponible. Le nouveau noyau continue à évoluer notamment sur la partie Rust qui est supporté sur le hrtimer et ARMv7. On bénéficie aussi d'un nouveau paramètre de boot s...

Merged this week for Linux 7.1 was a rework of the high resolution timer 'HRTIMER' subsystem for reducing the overhead of frequently-armed timers, such as the HRTICK scheduler timer

This is your friendly reminder that, as of today, the Linux 6.15 kernel series has reached the end of its supported life, which means that you should consider upgrading to Linux kernel 6.16 as soon as possible. Released on May 25th, 2025, **Linux kernel 6.15** introduced new features like Rust support for hrtimer and ARMv7, a new `setcpuid=` boot parameter for x86 CPUs, support for sched_ext to count and report internal events, x86 Intel and AMD PMU enhancements, nested virtualization support for VGICv3 on ARM, and support for emulating FEAT_PMUv3 on Apple Silicon. But, since Linux 6.15 is not a long-term support (LTS) branch, it is now marked as EOL (End of Life) on the _kernel.org_ website. The last maintenance release, Linux 6.15.11, was published today by renowned Linux kernel developer Greg Kroah-Hartman, who is now urging users to move to the latest Linux 6.16 kernel series as soon as possible. **Linux kernel 6.16** was released last month on July 28th, 2025, with new features like initial support for Intel Trusted Domain Extensions, support for Intel APX (Advanced Performance Extensions), USB offload support for audio devices, support for sending coredumps over an AF_UNIX socket, and an automatic auto-tuning weighted interleaved memory allocation policy. Linux 6.16 has already started to appear in the repositories of various popular distributions like openSUSE Tumbleweed and Arch Linux, but has also been adopted by other distros like the Slackware-based **PorteuX 2.2** , and it’s also coming soon to Fedora Linux users. However, Linux 6.16 is also a short-lived branch that will be supported for a couple of months only, so if you’re looking for long-term support, check out one of the many LTS kernels, including Linux kernel 6.12 LTS, which is the default kernel in **Debian 13 “Trixie”** , as well as Linux kernel 6.6 LTS and Linux kernel 6.1 LTS.

In the Linux kernel, the following vulnerability has been resolved: perf: Ensure swevent hrtimer is properly destroyed With the change to hrtimer_try_to_cancel() in perf_swevent_cancel_hrtimer() it appears possible for the hrtimer to still be active by the time the event gets freed. Make sure the event does a full hrtimer_cancel() on …

In the Linux kernel, the following vulnerability has been resolved: can: bcm: add locking for bcm_op runtime updates The CAN broadcast manager (CAN BCM) can send a sequence of CAN frames via hrtimer. The content and also the length of the sequence can be changed resp reduced at runtime where …
