Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The bcmgenet timeout handler incorrectly attempts to shut down all transmit (tx) queues when only a single queue experiences a timeout. This behavior creates race conditions—situations where the timing or order of events affects the correctness of the code—affecting queues that are still functioning normally.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
