Vulnerability from github – Published: 2026-08-10 15:33 – Updated: 2026-08-10 15:33

Details

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.
