CVE-2026-91780Hinoki check available

Local linker crash via null pointer dereference

Published Sep 15, 2026 · Updated Sep 15, 2026

Null pointer dereference in GNU Binutils 2.47 allows local users to crash the linker process via unspecified vectors. The elf_link_add_object_symbols function in bfd/elflink.c dereferences a null pointer, but public material does not identify the input or program state that produces it. Local execution is required, and the documented consequence is a linker-process crash rather than code execution or data modification.
