Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.2.7

Description The Linux kernel contained an issue in the ALSA subsystem, specifically within the ymfpci driver. A missing call to snd devm card new() after the removal of snd card ymfpci remove() resulted in a memory leak and potential Oops errors when unloading the module. This occurred because the snd card free function was no longer called, leading to unreleased resources.

Recommendations Update to Linux kernel version 6.2.7 or later.
