CVE-2025-40342 in Linux Kernel

Summary

In the Linux kernel, the following vulnerability has been resolved:

nvme-fc: use lock accessing port_state and rport state

nvme_fc_unregister_remote removes the remote port on a lport object at
any point in time when there is no active association. This races with
with the reconnect logic, because nvme_fc_create_association is not
taking a lock to check the port_state and atomically increase the
active count on the rport.
