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 within the
drm helper hpd irq event() function because it doesn't validate the drm device pointer. This issue is resolved by ensuring an HPD event is triggered only when the bridge is attached.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
