CVE-2024-23716

Kernel privilege escalation via driver use-after-free

Published Sep 11, 2024 · Updated Sep 12, 2024

Use-after-free in Google Android and Imagination Technologies Graphics DDK 23.3 and earlier allows local users to gain kernel privileges. A race in DevmemIntPFNotify in devicemem_server.c permits a freed object to be reused through a stale reference. Exploitation requires local access to a device using the affected PowerVR GPU driver, requires no user interaction, and can execute with kernel privileges.
