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

Description A flaw exists in the Linux kernel related to a deadlock in RSS configuration reading within the sfc module. The core now locks the net device's rss lock when handling the ethtool -x command, and driver implementations should not lock it again. The issue was addressed by removing the redundant locking mechanism.

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