Vulnerability from fkie_nvd - Published: 2024-06-19 14:15 - Updated: 2026-06-17 07:40
Severity
Summary
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.
