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

  - A vulnerability was identified in vim 9.1.0000. Affected is the function __memmove_avx_unaligned_erms of
    the file memmove-vec-unaligned-erms.S. The manipulation leads to memory corruption. The attack needs to be
    performed locally. The exploit is publicly available and might be used. Some users are not able to
    reproduce this. One of the users mentions that this appears not to be working, when coloring is turned
    on. (CVE-2025-9389)

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