Freed GPU memory access via use-after-free
Published Aug 5, 2024 · Updated Sep 30, 2024
Use-after-free in Arm Mali GPU kernel drivers r41p0 through r49p0 allows local users to access previously freed GPU memory. Arm states that improper GPU memory processing exposes already freed memory but has not disclosed the responsible function or precise lifetime error. A local non-privileged process must reach the GPU driver; the disclosed consequence is access to freed memory, while further exploitation behavior remains unpublished.

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 <=r49p0
- Affected versionversion=r41p0 <=r49p0 changes=[{"at":"r50p0","status":"unaffected"},{"at":"r49p1","status":"unaffected"}]
