Summary
drm/imagination: Free pvr_vm_gpuva after unlink
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/imagination: Free pvrvmgpuva after unlink

This caused a measurable memory leak. Although the individual allocations are small, the leaks occurs in a high-usage codepath (remapping or unmapping device memory) so they add up quickly.
