- Summary
- drm/i915: Fix NULL ptr deref by checking new_crtc_state
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Fix NULL ptr deref by checking newcrtcstate
intelatomicgetnewcrtcstate can return NULL, unless crtc state wasn't obtained previously with intelatomicgetcrtcstate, so we must check it for NULLness here, just as in many other places, where we can't guarantee that intelatomicgetcrtc_state was called. We are currently getting NULL ptr deref because of that, so this fix was confirmed to help.
