## Description

In the Linux kernel, the following vulnerability has been resolved:  drm/imagination: Break an object reference loop  When remaining resources are being cleaned up on driver close, outstanding VM mappings may result in resources being leaked, due to an object reference loop, as shown below, with each object (or set of objects) referencing the object below it:      PVR GEM Object     GPU scheduler "finished" fence     GPU scheduler “scheduled” fence     PVR driver “done” fence     PVR Context     PVR VM Context     PVR VM Mappings     PVR GEM Object  The reference that the PVR VM Context has on the VM mappings is a soft one, in the sense that the freeing of outstanding VM mappings is done as part of VM context destruction; no reference counts are involved, as is the case for all the other references in the loop.  To break the reference loop during cleanup, free the outstanding VM mappings before destroying the PVR Context associated with the VM context.
