Detailsinfo

A vulnerability was found in Google Android (Smartphone Operating System) (version unknown). It has been declared as problematic. This vulnerability affects the function PVRSRVBridgeDevicememHistorySparseChange of the component PowerVR Kernel Driver. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

In PVRSRVBridgeDevicememHistorySparseChange 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-270399633

The weakness was published 04/20/2023 as A-270399633. The advisory is available at source.android.com. This vulnerability was named CVE-2021-0874 since 11/06/2020.
