Detailsinfo

A vulnerability, which was classified as critical, was found in Google Android (Smartphone Operating System) (unknown version). Affected is an unknown code block of the component PowerVR Kernel Driver. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In PVRSRVBridgePMRPDumpSymbolicAddr 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-238921253

The weakness was disclosed 09/14/2022 as A-238921253. The advisory is available at source.android.com. This vulnerability is traded as CVE-2021-0871 since 11/06/2020. The technical details are unknown and an exploit is not available.
