CVE-2022-1048: Debian Linux

High severity, CVSS 7.0. EPSS: 0.2% chance of exploitation in the next 30 days.

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.
