  - In the Linux kernel, the following vulnerability has been resolved: net: use sock_gen_put() when sk_state
    is TCP_TIME_WAIT It is possible for a pointer of type struct inet_timewait_sock to be returned from the
    functions __inet_lookup_established() and __inet6_lookup_established(). This can cause a crash when the
    returned pointer is of type struct inet_timewait_sock and sock_put() is called on it. The following is a
    crash call stack that shows sk->sk_wmem_alloc being accessed in sk_free() during the call to sock_put() on
    a struct inet_timewait_sock pointer. To avoid this issue, use sock_gen_put() instead of sock_put() when
    sk->sk_state is TCP_TIME_WAIT. mrdump.ko ipanic() + 120 vmlinux notifier_call_chain(nr_to_call=-1,
