The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tcp: Fix out-of-bounds access for twsk in tcp_ao_established_key(). lockdep_sock_is_held() was added in     tcp_ao_established_key() by the cited commit. It can be called from tcp_v[46]_timewait_ack() with twsk.
    Since it does not have sk->sk_lock, the lockdep annotation results in out-of-bound access. $ pahole -C     tcp_timewait_sock vmlinux | grep size /* size: 288, cachelines: 5, members: 8 */ $ pahole -C sock vmlinux     | grep sk_lock socket_lock_t sk_lock; /* 440 192 */ Let's not use lockdep_sock_is_held() for     TCP_TIME_WAIT. (CVE-2026-64518)

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