In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: don't access released socket during error recovery
While the error recovery work is temporarily failing reconnect attempts,
running the 'nvme list' command causes a kernel NULL pointer dereference
by calling getsockname() with a released socket.
During error recovery work, the nvme tcp socket is released and a new one
created, so it is not safe to access the socket without proper check.
