Unspecified local impact via crafted relocation offset
Published Sep 14, 2026 · Updated Sep 14, 2026
Buffer overflow in GNU Binutils ld 2.47 allows local users to cause unspecified impact via a crafted x86-64 ELF relocation offset. The elf_x86_64_relocate_section function processes the attacker-controlled roff value without sufficient bounds validation, causing an out-of-bounds buffer operation in bfd/elf64-x86-64.c. The attack requires local access and a crafted object supplied to ld; the public record does not establish effects beyond the affected linker process.
