Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use after free (UAF) issue exists in the arm mpam driver. This occurs when a user unbinds a Memory System Component (MSC) that is the sole remaining MSC for a component, causing the associated
mpam component to be freed. Subsequently, accessing the schemata file within the resctrl filesystem triggers the resctrl arch get config() function, which attempts to access the already freed mpam component.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
