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

  - xen/events: Return -EEXIST for bound VIRQs Change find_virq() to return -EEXIST when a VIRQ is bound to a     different CPU than the one passed in. With that, remove the BUG_ON() from bind_virq_to_irq() to propogate     the error upwards. Some VIRQs are per-cpu, but others are per-domain or global. Those must be bound to     CPU0 and can then migrate elsewhere. The lookup for per-domain and global will probably fail when migrated     off CPU 0, especially when the current CPU is tracked. This now returns -EEXIST instead of BUG_ON(). A     second call to bind a per-domain or global VIRQ is not expected, but make it non-fatal to avoid trying to     look up the irq, since we don't know which per_cpu(virq_to_irq) it will be in. (CVE-2025-40160)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1316 advisory.
