CVE-2026-68202

The CVE describes a vulnerability in the Linux kernel ALSA seq subsystem where a re-opened queue timer can be re-created after queue destruction. Specifically, queue_delete() frees the timer after closing it, but snd_seq_timer_delete() may leave an active instance if the window between close and ...

CVE-2026-68201

ALSA timer use-after-free in the Linux kernel (CVE-2026-68201): when a master timer is closed, the slaves’ callbacks could still be running and be freed underneath them. The fix drains the slaves’ callbacks before remove_slave_links(), removes slaves from the ack list, and waits for in-flight cal...

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: drain a slave's callback before its master detaches it sndtimercloselocked drains the closing instance's own in-flight callback IFLGCALLBACK before freeing it, but not its slaves'. When a master instance is closed,...

EUVD-2026-55301

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: don't re-enter an instance callback that is still running The userspace-driven timer utimer TRIGGER ioctl calls sndtimerinterrupt directly with no serialization, so two threads triggering the same utimer can run...

CVE-2026-68200

The Linux kernel ALSA timer vulnerability CVE-2026-68200 allows a use-after-free when a utimer callback is still running and a second interrupt re-queues the same instance. The fix prevents re-queuing an in-flight callback by not adding it (and its slaves) to the ack/sack list while the callback ...
