Local freed-memory access via valid GPU operations
Published Sep 8, 2026 · Updated Sep 8, 2026
Use-after-free in Arm Mali GPU kernel drivers r50p0 through r54p3 and r55p0 allows local users to access freed memory. The kernel driver processes otherwise valid GPU operations against a memory object after that object has already been freed. The gate is a non-privileged local process able to issue GPU operations, while Arm publishes no more specific consequence than freed-memory access.

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=r50p0 <=r54p3
- Affected versionversion=r55p0
