Kernel privilege escalation via improper casting
Published Jan 28, 2025 · Updated Jan 28, 2025
Use-after-free in Android SoC PowerVR-GPU code allows local users to gain kernel privileges through an affected graphics driver. _DevmemXReservationPageAddress in devicemem_server.c performs an improper cast that causes code to access memory after it has been freed. Exploitation requires local execution on a device with the affected Imagination Technologies PowerVR GPU component, but needs neither prior execution privileges nor user interaction.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
