CVE-2022-50305

24
FAUCET Score

CVE-2022-50305 is a high-severity use-after-free vulnerability in the Linux kernel's ASoC sof_es8336 driver. This flaw, rated 7.8 CVSS, arises because the sof_es8336_remove() function fails to properly synchronize work cancellation, potentially allowing a callback function to execute after the driver has been removed. A local attacker with low privileges could exploit this to achieve high impact on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
