Kernel code execution via stale queue page freeing
Published May 2, 2025 · Updated May 12, 2025
Use-after-free in Arm Mali GPU kernel drivers allows local users to execute arbitrary code in kernel context through crafted queue operations. Rebinding a kbase_queue replaces queue->phys pages, after which closing an older mapping frees the replacement pages while a newer mapping still exposes them. A non-privileged local process with access to the Mali device can turn the dangling mapping into kernel memory access and kernel code execution.

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.
