9.8

CVSS v3.1

Official Description

In PVRSRVBridgeSyncPrimOpCreate of the PowerVR kernel driver, a missing size check means there is a possible integer overflow that could allow out-of-bounds heap access. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
