kernel: Linux kernel: ALSA timer use-after-free vulnerability allows privilege escalation

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A lack of serialization in the userspace-driven timer utimer TRIGGER ioctl allows two threads to concurrently call sndtimerinterrupt. This race condition can lead to a use-after-free vulnerability, wher...
