Kernel memory access via valid GPU operations
Published May 2, 2025 · Updated May 12, 2025
Use-after-free in Arm Mali GPU Kernel Drivers allows local users to access freed kernel memory through valid GPU processing operations. Arm has not published the affected object or the allocation and release path that mishandles its lifetime. A local non-privileged process with GPU device access is required, and the disclosed consequence is stale-memory access rather than a stated code-execution primitive.

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=r19p0 <=r49p3 changes=[{"at":"r49p4","status":"unaffected"}]
- Affected versionversion=r50p0 <=r53p0 changes=[{"at":"r54p0","status":"unaffected"}]
