Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:
16/09/2025
Last modified:

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 /> Patchwork: https://patchwork.freedesktop.org/patch/665188/
