CVE-2021-47281 ALSA: seq: Fix race of snd_seq_timer_open()

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix race of sndseqtimeropen The timer instance per queue is exclusive, and sndseqtimeropen should have managed the concurrent accesses. It looks as if it's checking the already existing timer instance at the beginning,...

kernel: use-after-free in sound/core/timer.c

A memory flaw was found in the ALSA subsystem of the Linux kernel. The struct sndtimerinstance function fails the timer-maxinstances check leading to an invalid address. This could lead to a use-after-free vulnerability...
