Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011212 advisory.

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

    bpf, sockmap: Fix memleak in sk_psock_queue_msg

    If tcp_bpf_sendmsg is running during a tear down operation we may enqueue     data on the ingress msg queue while tear down is trying to free it.

     sk1 (redirect sk2)                         sk2
     -------------------                      ---------------     tcp_bpf_sendmsg()      tcp_bpf_send_verdict()       tcp_bpf_sendmsg_redir()        bpf_tcp_ingress()                                               sock_map_close()                                                lock_sock()         lock_sock() ... blocking                                                sk_psock_stop                                                 sk_psock_clear_state(psock, SK_PSOCK_TX_ENABLED);
                                               release_sock(sk);

          drop_sk_msg()         release_sock()

    While drop_sk_msg(), the msg has charged memory form sk by sk_mem_charge     and has sg pages need to put. To fix we use sk_msg_free() and then kfee()     msg.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013859 advisory.

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

    bpf, sockmap: Fix memleak in sk_psock_queue_msg

    If tcp_bpf_sendmsg is running during a tear down operation we may enqueue     data on the ingress msg queue while tear down is trying to free it.

     sk1 (redirect sk2)                         sk2
     -------------------                      ---------------     tcp_bpf_sendmsg()      tcp_bpf_send_verdict()       tcp_bpf_sendmsg_redir()        bpf_tcp_ingress()                                               sock_map_close()                                                lock_sock()         lock_sock() ... blocking                                                sk_psock_stop                                                 sk_psock_clear_state(psock, SK_PSOCK_TX_ENABLED);
                                               release_sock(sk);
        lock_sock()         sk_mem_charge()         get_page()         sk_psock_queue_msg()          sk_psock_test_state(psock, SK_PSOCK_TX_ENABLED);
          drop_sk_msg()         release_sock()

    While drop_sk_msg(), the msg has charged memory form sk by sk_mem_charge     and has sg pages need to put. To fix we use sk_msg_free() and then kfee()     msg.

    This issue can cause the following info:
