Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/msm/dpu: Add a null ptr check for dpu_encoder_needs_modeset<br />
<br />
The drm_atomic_get_new_connector_state() can return NULL if the<br />
connector is not part of the atomic state. Add a check to prevent<br />
a NULL pointer dereference.<br />
<br />
This follows the same pattern used in dpu_encoder_update_topology()<br />
within the same file, which checks for NULL before using conn_state.<br />
<br />
