Last modified
CVE-2022-49538 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ALSA: jack: Access input_dev under mutex It is possible when using ASoC that input_dev is unregistered while calling snd_jack_report, which causes NULL pointer dereference. In order to prevent this serialize access to input_dev using mutex lock.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
