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

  - systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an     unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an     assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is     not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions     older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known     workarounds are available. (CVE-2026-29111)

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