Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the USB Type-C Thunderbolt implementation where the
tbt altmode remove() function drops plug and cable references without draining tbt->work. Because the work function dereferences these references and can requeue itself during error paths or via VDM callbacks, this can lead to a use-after-free scenario during teardown.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
