  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/imagination: fix error checking of pvr_vm_context_lookup()  Since pvr_vm_context_lookup() returns either NULL or a pointer, then stop using IS_ERR() for checking the return value.  Using IS_ERR() leads to the kernel oops reported below. It can be reproduced by passing an invalid VM context handle from userspace to the DRM_IOCTL_PVR_CREATE_CONTEXT ioctl.
