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

  - A vulnerability has been found in GNU Binutils 2.45. The affected element is the function elf_swap_shdr in
    the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow.
    The attack must be carried out locally. The exploit has been disclosed to the public and may be used. The
    identifier of the patch is 9ca499644a21ceb3f946d1c179c38a83be084490. To fix this issue, it is recommended
    to deploy a patch. The code maintainer replied with [f]ixed for 2.46. (CVE-2025-11083)

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