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

  - A flaw was found in the IPv6 module of the Linux kernel. The arg.result was not used consistently in     fib6_rule_lookup, sometimes holding rt6_info and other times fib6_info. This was not accounted for in     other parts of the code where rt6_info was expected unconditionally, potentially leading to a kernel panic     in fib6_rule_suppress. (CVE-2023-3022)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004282 advisory.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:1975 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.
