Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Thunderbolt networking driver in the Linux kernel. When a discrete host router NVM upgrade is performed and the router is hot-removed from the PCIe side due to NVM firmware authentication, the system may hang while tearing down enabled paths. This is because the Thunderbolt networking driver attempts to clean up the paths and ends up blocking in
tb disconnect xdomain paths() while waiting for the domain lock. However, since the paths have already been cleaned in tb stop(), there is no need for tb disconnect xdomain paths() to perform this action. The fix involves marking the XDomain as unplugged when the parent router is removed. The vulnerability may allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
