CVE-2026-68202

CVE-2026-68202 affects the Linux kernel’s ALSA sequencer. A race in queue timer cleanup allows an unprivileged local user with access to /dev/snd/seq to re-open a timer that has just been closed, leading to a use-after-free of the timer/queue object and a potential crash or, in theory, arbitrary ...

CVE-2026-68201

The CVE-2026-68201 issue affects the Linux kernel ALSA timer: when closing a master timer, a slave’s in-flight callback may run after detach, causing use-after-free. The fix drains slave callbacks before removing slave links, and stops pending/active callbacks on the slave side before freeing. Th...
