HighCVSS 7.8/10Last modified Jun 17, 2026

Description

In PVRSRVBridgePhysmemNewRamBackedLockedPMR 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.Product: AndroidVersions: Android SoCAndroid ID: A-270400229
