In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Forcibly close timer instances at closing When sndtimer object is freed via sndtimerfree and still pending sndtimerinstance objects are assigned to the timer object, it tries to unlink all instances and just set NULL...

CVE-2026-53193

CVE-2026-53193 concerns the Linux kernel ALSA timer component. When a snd_timer object is freed via snd_timer_free() while there are still pending snd_timer_instance entries linked to it, slave instances may continue to point at the freed timer, creating a use-after-free condition. The vulnerabil...
