Out-of-bounds access via valid GPU operations
Published Apr 7, 2025 · Updated Apr 10, 2025
Out-of-bounds access in Arm Mali GPU userspace drivers allows local users to read or write limited data beyond GPU buffer boundaries. The drivers permit otherwise valid GPU operations, including WebGL or WebGPU workloads, to cross a buffer boundary; Arm has not disclosed the responsible routine. Affected releases are Bifrost r0p0 through r49p2 and r50p0 through r51p0, Valhall r19p0 through r49p2 and r50p0 through r53p0, and 5th Gen r41p0 through r49p2 and r50p0 through r53p0.

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=r0p0 <=r49p2 changes=[{"at":"r49p3","status":"unaffected"}]
- Affected versionversion=r50p0 <=r51p0
