Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A possible NULL dereference vulnerability has been identified in the Linux kernel, specifically in the ALSA core. The issue is caused by the function kunit kzalloc(), which may return a NULL pointer. Without a NULL check, dereferencing this pointer can lead to a NULL dereference. To address this issue, NULL checks have been added for all kunit kzalloc() calls in sound kunit.c.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
