Linux Kernel: Late-Cycle Fixes Converge on Rc5
This is a quiet, late-stage bug-fix cycle heading into rc5 - four merges covering watchdog, sound, x86 platform drivers, and live update, most of which fix use-after-free bugs, null pointer checks, and error-path cleanups rather than new features. The standout is a userspace-compatibility revert in the ASUS WMI driver, a reminder that kernel-side "fixes" can break real-world tooling.

Good day, it's July 23rd, 2026, and this is your Linux Kernel briefing.
The signal this cycle is defensive cleanup. Across four merges, the common thread is memory safety and error handling on paths that rarely get exercised - exactly the kind of bugs that surface late in a release cycle.
Start with watchdog fixes, commit 08de7d9. Guenter Roeck's pull brings a division-by-zero guard in the Airoha driver when clock frequency is zero, a use-after-free fix in the pretimeout governor unregistration path, and a null check on ACPI companion lookups in the ni903x driver. Different drivers, same category of…
That pattern repeats in sound, commit 57a92aa. Takashi Iwai's pull includes two ALSA timer core fixes - draining a slave's callback before its master detaches, and preventing re-entry into a still-running instance callback. Both are race and use-after-free fixes in core timer code, not quirks. The rest of the pull…
The platform drivers pull, commit d0ec222, is smaller but worth flagging for a different reason. The ASUS WMI driver is reverting a change that made battery charge threshold settings persist across boot. The kernel change was technically fine, but userspace tooling misread a…
