  - In the Linux kernel, the following vulnerability has been resolved: smb: client: fix TCP timers deadlock
    after rmmod Commit ef7134c7fc48 (smb: client: Fix use-after-free of network namespace.) fixed a netns
    UAF by manually enabled socket refcounting (sk->sk_net_refcnt=1 and sock_inuse_add(net, 1)). The reason
    the patch worked for that bug was because we now hold references to the netns (get_net_track() gets a ref
    internally) and they're properly released (internally, on __sk_destruct()), but only because
    sk->sk_net_refcnt was set. Problem: (this happens regardless of CONFIG_NET_NS_REFCNT_TRACKER and
    regardless if init_net or other) Setting sk->sk_net_refcnt=1 *manually* and *after* socket creation is not
    only out of cifs scope, but also technically wrong -- it's set conditionally based on user (=1) vs kernel
    (=0) sockets. And net/ implementations seem to base their user vs kernel space operations on it. e.g. upon
    TCP socket close, the TCP timers are not cleared because sk->sk_net_refcnt=1: (cf. commit 151c9c724d05
    (tcp: properly terminate timers for kernel sockets)) net/ipv4/tcp.c: void tcp_close(struct sock *sk,
    long timeout) { lock_sock(sk); __tcp_close(sk, timeout); release_sock(sk); if (!sk->sk_net_refcnt)
    inet_csk_clear_xmit_timers_sync(sk); sock_put(sk); } Which will throw a lockdep warning and then, as
    expected, deadlock on tcp_write_timer(). A way to reproduce this is by running the reproducer from
    ef7134c7fc48 and then 'rmmod cifs'. A few seconds later, the deadlock/lockdep warning shows up. Fix: We
    shouldn't mess with socket internals ourselves, so do not set sk_net_refcnt manually. Also change
    __sock_create() to sock_create_kern() for explicitness. As for non-init_net network namespaces, we deal
    with it the best way we can -- hold an extra netns reference for server->ssocket and drop it when it's
    released. This ensures that the netns still exists whenever we need to create/destroy server->ssocket, but
    is not directly tied to it. (CVE-2024-54680)

Note that Nessus relies on the presence of the package as reported by the vendor.");
