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

  - editorconfig-core-c is an EditorConfig core library for use by plugins supporting EditorConfig parsing.
    Versions up to and including 0.12.10 have a stack-based buffer overflow in ec_glob() that allows an     attacker to crash any application using libeditorconfig by providing a specially crafted directory     structure and .editorconfig file. This is an incomplete fix for CVE-2023-0341. The pcre_str buffer was     protected in 0.12.6 but the adjacent l_pattern[8194] stack buffer received no equivalent protection. On     Ubuntu 24.04, FORTIFY_SOURCE converts the overflow to SIGABRT (DoS). Version 0.12.11 contains an updated     fix. (CVE-2026-40489)

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