Local memory disclosure and modification via use-after-free

Use-after-free in Arm Mali GPU Kernel Drivers allows local users to access freed memory through valid GPU memory-processing operations. Arm reports that a non-privileged process performs otherwise valid GPU memory-processing operations after the driver frees the referenced memory, but it does not disclose the responsible function or lifetime transition. Local access to the Mali GPU device interface is required; the published impact is limited to disclosure and modification of freed memory, with no reported service interruption.
