Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description In PVRSRVBridgeHeapCfgHeapConfigName, there is a possible leak of kernel heap content due to uninitialized data. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to sensitive kernel heap content to minimize the risk of exploitation. As a temporary workaround, review and restrict any unnecessary use of the PVRSRVBridgeHeapCfgHeapConfigName until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
