CVE-2026-53278

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

Description A NULL pointer dereference occurs when the destroy component cfg() function is called from mpam disable() before the configuration array has been allocated. The function attempts to use an embedded garbage structure to free the configuration array and the mbwu state (allocated by allocate component cfg()), but it fails to verify if the array exists first.

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