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

  - futex/pi: Reject cross-mm private futex owners A private futex key borrows the waiter's mm without taking     an mm_users reference. Nevertheless, attach_to_pi_owner() currently accepts an owner from a different     address space and copies the private key into the owner's PI state. When that owner exits,     exit_pi_state_list() uses the saved key to find the hash bucket and acquires a reference to the waiter's     private hash. If the last user of the waiter's mm exits concurrently, futex_hash_free() frees the hash     while the owner still uses its bucket and reference. Prevent this by validating in attach_to_pi_owner()     that, for private futexes, the owner mm and waiter mm are the same. Perform the check with the owner's     pi_lock held and after validating owner::futex::state to serialize against a concurrent PI-state exit     cleanup. [ tglx: Amended comment ] (CVE-2026-80778)

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