Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the DisplayPort driver's sysfs nodes being present to the userspace before the completion of
typec altmode set drvdata() in dp altmode probe(). This can trigger a NULL pointer error by deferencing dp->hpd in hpd show() or dp->lock in pin assignment show(), as dev get drvdata() returns NULL in those cases. The problem is resolved by removing manual sysfs node creation in favor of adding an attribute group as default for devices bound to the driver.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
