Local freed GPU memory access via use-after-free
Published May 3, 2024 · Updated Aug 1, 2024
Use-after-free in Arm 5th Gen GPU Architecture Kernel Driver r41p0 through r47p0 allows local users to access freed GPU memory. Arm has not published the affected function; the driver improperly processes GPU memory operations and permits access after memory is freed. Exploitation requires non-privileged local access and carefully prepared system memory, exposing freed contents without a reported 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=r41p0 <=r47p0
- Affected versionversion=r41p0 <=r47p0 changes=[{"at":"r48p0","status":"unaffected"}]
