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

  - s390/ipl: Fix NULL deref in dump_reipl without re-IPL parm block Unlike kdump, which passes the re-IPL     parameter block through os_info, the stand-alone dump passes it through the IPL parm block address and     checksum in lowcore. Some IPL types, like HMC FTP boot or QEMU direct kernel boot, might not provide an     IPL parameter block. In this case reipl_type_init() selects IPL_TYPE_UNKNOWN and reipl_block_actual     remains NULL. Nevertheless, dump_reipl_run() unconditionally dereferences it when preparing the lowcore     fields. This may happen to work by chance when address zero contains readable lowcore data. A zero IPL     parameter block address is then stored in lowcore, causing the stand-alone dumper to enter disabled wait     after completing the dump. Explicitly store a zero IPL parameter block address and checksum when no re-IPL     parameter block is available. This does not change the behavior: the stand-alone dumper completes the dump     and halts, while valid re-IPL parameter blocks continue to be handled as before. (CVE-2026-98399)

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