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.
