Null Pointer Dereference in Linux Kernel ALSA - Affected Products

CVE-2026-64488

What is CVE-2026-64488?

A vulnerability in the Linux kernel's ALSA component can cause a NULL pointer dereference due to insufficient checks after memory allocation for sound control elements. When the snd_ctl_new1() function fails to allocate memory, the absence of checks can lead to dereferencing a null pointer, potentially causing unexpected behavior or system crashes. Proper validation protocols must be implemented to ensure robust handling of memory allocation failures.
