CVE-2026-64484

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

Description In the ALSA es1938 component, the function snd es1938 mixer() fails to verify the return value of snd ctl new1(). If memory allocation fails, snd ctl new1() returns NULL, and the subsequent dereferencing of this pointer leads to a NULL pointer dereference, which is a condition where the software attempts to read or write to a memory address that is null, typically causing a system crash.

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