Description OSIDB Bzimport 2026-02-14 17:03:12 UTC 
In the Linux kernel, the following vulnerability has been resolved:

sfc: fix deadlock in RSS config read

Since cited commit, core locks the net_device's rss_lock when handling
 ethtool -x command, so driver's implementation should not lock it
 again.  Remove the latter.
