CVE-2022-49842

CVE-2022-49842: In the Linux kernel’s ASoC core, a use-after-free in snd_soc_exit() was fixed. The root cause was a missing error check in snd_soc_init() where snd_soc_util_init() could fail and return value was ignored, causing soc_dummy_dev to be unregistered twice. The fix requires handling er...
