CVE-2026-53058

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A NULL pointer dereference can occur in the recovery paths of the cadence cdns-mhdp8546-core driver. When errors occur in the cdns mhdp link up() or cdns mhdp reg read() functions during atomic enable(), the system calls cdns mhdp modeset retry fn(). If the DRM BRIDGE ATTACH NO CONNECTOR flag is set, the connector is not initialized in bridge attach(), leading to a NULL pointer access when attempting to access the mutex.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
