CVE-2024-32891

Local privilege escalation via sec_media_unprotect race

Published Jun 13, 2024 · Updated Aug 2, 2024

Memory corruption in Google Android before the 2024-06-05 patch level allows local users to gain elevated privileges. The sec_media_unprotect function in media.c improperly synchronizes concurrent access, creating a race that corrupts memory. Exploitation requires existing low-privileged local access but no user interaction, and successful use grants higher privileges on the device.
