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

  - An out-of-bounds heap write exists in the RAR5 recovery-volume (.rev) parser in WinRAR and UnRAR     (RecVolumes5::ReadHeader in recvol5.cpp). The RecItems vector is sized only when the first .rev file in a     set is processed; subsequent .rev files supply an independent RecNum value that is validated against that     file's own TotalCount field but never against the actual size of RecItems. A crafted set of two or more     .rev files can therefore write an attacker-controlled 32-bit value (the header's RevCRC field) to     RecItems[RecNum] at an attacker-controlled offset up to 65534 * sizeof(RecVolItem) bytes past the     allocation, corrupting adjacent heap objects. Triggering requires the victim to run a recovery/test     operation on an attacker-supplied .rev set (for example 'unrar t x.part1.rev', WinRAR 'Repair archive', or     auto-recovery when extracting a volume set with a missing .rar part). This is the RAR5-path sibling of     CVE-2023-40477 (which was fixed in the RAR3 path only in WinRAR 6.23). Fixed in WinRAR / RAR 7.23.
    (CVE-2026-14191)

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