Freed kernel-memory access via improper GPU operations
Published Feb 3, 2025 · Updated Feb 3, 2025
Use-after-free in Arm Valhall and 5th Gen GPU kernel drivers allows local users to access freed kernel memory through GPU operations. Arm has not published the responsible function or lifetime error; its advisory states only that improper GPU processing operations access memory after release. A local non-privileged process with GPU device access is required, and successful exploitation can compromise kernel-memory confidentiality, integrity, and availability.

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 <=r49p1 changes=[{"at":"r49p2","status":"unaffected"}]
- Affected versionversion=r50p0 <=r52p0 changes=[{"at":"r53p0","status":"unaffected"}]
