Vulnerability from github – Published: 2026-09-15 09:30 – Updated: 2026-09-15 09:30

Details

A security flaw has been discovered in GNU Binutils 2.47. This affects the function _bfd_elf_eh_frame_section_offset of the file bfd/elf-eh-frame.c of the component Eh Frame Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet.
