This CVE record has recently been published to the CVE List and has been included within the NVD dataset.

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.
