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

  - net: openvswitch: fix possible kfree_skb of ERR_PTR After the patch in the Fixes tag, the allocation of     the reply skb can happen either before or after locking the ovs_mutex. However, error cleanups still     follow the classical reversed order, assuming reply is allocated before locking: it is freed after     unlocking. If reply allocation happens after locking the mutex and it fails, reply is left with an     ERR_PTR, and execution jumps to the correspondent cleanup stage which will try to free an invalid pointer.
    Fix this by setting the pointer to NULL after having saved its error value. (CVE-2026-53227)

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