In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Free pvr_vm_gpuva after unlink This caused a measurable memory leak.

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
