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

  - net: dsa: remove redundant netdev_lock_ops() from conduit ethtool ops DSA replaces the conduit (master)     device's ethtool_ops with its own wrappers that aggregate stats from both the conduit and DSA switch     ports. Taking the lock again inside the DSA wrappers causes a deadlock. Stumbled upon this when booting     qemu with fbnic and CONFIG_NET_DSA_LOOP=y (which looks like some kind of testing device that auto-     populates the ports of eth0). `ethtool -i` is enough to deadlock. This means we have basically zero     coverage for DSA stuff with real ops locked devs. Remove the redundant     netdev_lock_ops()/netdev_unlock_ops() calls from the DSA conduit ethtool wrappers. (CVE-2026-53323)

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