Description OSIDB Bzimport 2026-09-17 17:43:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

octeontx2-vf: fix workqueue and netdev race in probe/remove

Initialize the VF workqueue before register_netdev() so ndo_set_rx_mode
does not queue work on a NULL workqueue. Unregister the netdev before
destroying the workqueue, and add proper probe error cleanup.
