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...

kernel: ALSA: timer: Fix UAF at snd_timer_user_params()

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A race condition can occur during the release of a timer object, specifically when the SNDRVTIMERIOCTLPARAMS ioctl is called concurrently. This can lead to a use-after-free vulnerability, potentially...

kernel: ALSA: seq: Serialize UMP output teardown with event_input

A flaw was found in the Advanced Linux Sound Architecture ALSA sequencer component of the Linux kernel. This vulnerability, a use-after-free, occurs because of improper synchronization when handling Universal MIDI Packet UMP output. A local attacker could exploit this by creating a specific timin...
