In the Linux kernel, the following vulnerability has been resolved:drm/imagination: fix firmware memory leaksFree the memory used to hold the results of firmware image processing
when the module is unloaded.Fix the related issue of the same memory being leaked if processing
of the firmware image fails during module load.Ensure all firmware GEM objects are destroyed if firmware image
processing fails.Fixes memory leaks on powervr module unload detected by Kmemleak:unreferenced object 0xffff000042e20000 (size 94208):
