Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference

In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is

assigned to mhdp_state->current_mode, and there is a dereference of it in

drm_mode_set_name(), which will lead to a NULL pointer dereference on

failure of drm_mode_duplicate().

Fix this bug add a check of mhdp_state->current_mode.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
