Good day, and welcome to Linux Kernel Daily for July 23rd, 2026.
Today's activity is all late-stage rc5 cleanup, and the throughline is memory safety. Three separate subsystems fixed use-after-free or missing-null-check bugs this cycle, a reminder that these bugs remain the most common class of late-cycle kernel fixes.
Start with watchdog, pulled in commit zero-eight-d-e-seven-d-nine. Guenter Roeck's tree fixes a use-after-free in the pretimeout governor unregister path, plus a null check missing for an ACPI companion lookup in the N-I-nine-oh-three-x driver, and a divide-by-zero guard for the Airoha driver when clock frequency…
Sound followed the same pattern. Takashi Iwai's pull, commit five-seven-a-nine-two-a-a, bundles twenty-five commits, but the core ALSA timer fixes stand out: a race where a slave timer's callback wasn't drained before its master detached, and a re-entrancy bug where a timer callback could be invoked while already…
Platform drivers, commit d-zero-e-c-two-two-two, take a different approach: rather than fix forward, Ilpo Järvinen's tree reverts a recent change to the Asus WMI battery charge threshold behavior. Userspace code made a wrong assumption about a…
