Summary
The method PVRSRVBridgePMRPDumpSymbolicAddr allocates puiMemspaceNameInt on the heap, fills the contents of the buffer via PMR_PDumpSymbolicAddr, and then copies the buffer to userspace. The method PMR_PDumpSymbolicAddr may fail, and if it does the buffer will be left uninitialized and despite the error will still be copied to userspace. Kernel leak of uninitialized heap data with no privs required.Product: AndroidVersions: Android SoCAndroid ID: A-236846966
