Freed-memory disclosure through valid GPU processing
Published Aug 4, 2025 · Updated Feb 26, 2026
Use-after-free in Arm Mali GPU userspace drivers allows remote authenticated users to read freed memory through WebGL or WebGPU. Arm has not disclosed the allocation, object, or function whose lifetime is mishandled; the public record states only that valid GPU processing operations access already freed memory. Exploitation requires a non-privileged process able to submit GPU work, and the published assessment limits impact to disclosure without data modification or service interruption.

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=r48p0 <=r49p3 changes=[{"at":"r49p4","status":"unaffected"}]
- Affected versionversion=r50p0 <=r51p0 changes=[{"at":"r54p1","status":"unaffected"}]
