Freed-memory disclosure via improper GPU operations
Published Apr 19, 2024 · Updated Aug 1, 2024
Use-after-free in Arm Mali GPU Kernel Drivers r45p0 through r48p0 allows local users to read previously freed memory via GPU operations. The drivers process attacker-controlled GPU memory operations after the referenced memory has been freed, exposing stale allocations. A local non-privileged process is required; the bounded consequence is access to freed memory, with no published claim of code execution 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=r45p0 <=r48p0
- Affected versionversion=r45p0 <=r48p0 changes=[{"at":"r49p0","status":"unaffected"}]
