Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL pointer dereference occurs in the arm mpam module when a user unbinds a Memory System Component (MSC) after an error interrupt has triggered the
mpam disable() function. This happens because mpam disable() sets the drvdata variable to NULL, and the subsequent unbinding process attempts to dereference it.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
