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

  - x86/bugs: Make Safe-RET robust against interrupt injection An attacker injecting interrupts while the     Safe-RET mitigation executes on machines affected by SRSO can neutralize the safe return sequence,     potentially leading to data leakage through speculative execution. Fixup register state as if the Safe-RET     sequence executed successfully by emulating it, in a manner of speaking, and avoid executing a RET     instruction after returning from the interrupt. (CVE-2026-68480)

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