"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-1301 advisory.

    A vulnerability has been found in GNU Binutils 2.45. This impacts the function bfd_elf_gc_record_vtentry
    of the file bfd/elflink.c of the component Linker. The manipulation leads to out-of-bounds read. Local
    access is required to approach this attack. The exploit has been disclosed to the public and may be used.
    The identifier of the patch is 047435dd988a3975d40c6626a8f739a0b2e154bc. To fix this issue, it is
    recommended to deploy a patch. (CVE-2025-11412)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
