CVE-2024-40671

Local privilege escalation via unchecked device-memory changes

Published Nov 13, 2024 · Updated Nov 14, 2024

Missing authorization in Android SoC PowerVR-GPU code allows local users to gain elevated privileges through arbitrary code execution. DevmemIntChangeSparse2 in devicemem_server.c changes sparse device-memory mappings without the required permission check. A low-privileged local user can reach the flaw without user interaction and execute code with elevated privileges on affected devices.
