Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue where the alx driver does not hold the rtnl lock during its internal close and re-open functions during suspend/resume operations. This can lead to an rtnl assertion failure. The issue occurs when resuming from suspend, specifically triggering an assertion in net/core/dev.c. The driver implements its own locking and does not change the number of queues, but the assertion needs to be silenced.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
