Parent graphics-buffer disclosure via recycled process handles
Published Nov 18, 2024 · Updated Nov 18, 2024
Information disclosure in Imagination Technologies Graphics DDK 1.13 RTM through 24.2 RTM1 allows local users to read a parent's graphics buffers. PVRSRVAcquireProcessHandleBase reuses psProcessHandleBase when process identifiers are recycled, associating a child with stale parent handle state. A non-privileged local process must issue improper GPU system calls on a Linux or Android device using the affected PowerVR driver.

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?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.13_rtm <=24.2_rtm1
- Affected versionversion=1.13 RTM <=24.2 RTM1
- Affected versionversion=24.2_rtm
