CVE-2022-1048 is a race-condition-driven use-after-free vulnerability in the Linux kernel ALSA PCM sound subsystem. In snd_pcm_hw_free, locking can be released too early while concurrent PCM hw_params, hw_free, or related ioctl operations are processed. The resulting unsynchronized object lifetime handling may permit access to freed memory.
