Description
An issue exists in the arm64 architecture regarding the Memory Tagging Extension (MTE) store-only tag check mode. When a user opts into this mode, the
SCTLR EL1.TCSO0 bit is set. Because this bit is not included in the SCTLR USER MASK, it is not cleared during a context switch, causing the setting to leak into another task.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
