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

drm/imagination: Propagate map failures correctly from pvr_mmu_map_sgl()

Map failure from pvr_mmu_map_sgl() interface was not returned correctly to pvr_mmu_map() interface. This resulted in pvr_mmu_map() interface to continue instead of returning an error to caller. Fix it by returning a proper error code from pvr_mmu_map_sgl() interface.
