Name of the Vulnerable Software and Affected Versions PowerVR kernel driver versions (affected versions not specified) Android SoC versions (affected versions not specified)

Description The issue is related to a missing size check in the PowerVR kernel driver, which could lead to an integer overflow and out-of-bounds heap access. This could result in local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For the PowerVR kernel driver, apply a patch that includes a size check to prevent integer overflow. For Android SoC, update to a version that includes the fix for the missing size check issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
