Freed-memory access via valid GPU operations
Published Sep 8, 2026 · Updated Sep 8, 2026
Use after free in Arm Mali GPU userspace drivers allows local users to read freed memory through valid GPU processing operations. Arm has not published the driver function or lifetime error that leaves the GPU-accessible allocation reachable after it is freed. A non-privileged process can trigger the flaw with valid GPU work, including WebGL or WebGPU, exposing stale memory contents.

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=r42p0 <=r49p5
- Affected versionversion=r50p0 <=r51p0
- Affected versionversion=r54p1 <=r54p3
