- Summary
- drm/msm/dpu: Add a null ptr check for dpu_encoder_needs_modeset
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Add a null ptr check for dpuencoderneeds_modeset
The drmatomicgetnewconnector_state() can return NULL if the connector is not part of the atomic state. Add a check to prevent a NULL pointer dereference.
This follows the same pattern used in dpuencoderupdatetopology() within the same file, which checks for NULL before using connstate.
