However when the interrupts trigger the bridge might not have been...

CVE-2023-53389

CVE-2023-53389 affects the Linux kernel’s MediaTek DisplayPort bridge (drm/mediatek) where HPD IRQs could fire before the bridge is attached to a DRM device. This could cause a NULL pointer dereference in drm_helper_hpd_irq_event() due to an invalid drm_device being passed. The published fix: ver...

PT-2025-38368

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The MediaTek DisplayPort interface bridge driver initiates interrupts immediately after probing. If the bridge isn't yet connected to a DRM device, a NULL pointer dereference can occur...
