Detailsinfo

A vulnerability classified as problematic has been found in Google Android (Smartphone Operating System) (the affected version is unknown). This affects the function PVRSRVBridgeSyncPrimOpTake 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. The summary by CVE is:

In PVRSRVBridgeSyncPrimOpTake 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-270401914

The weakness was released 04/20/2023 as A-270401914. The advisory is shared at source.android.com. This vulnerability is uniquely identified as CVE-2021-0885 since 11/06/2020.
