CVE-2025-11414Public exploitHinoki check available

Linker crash via unsorted ELF symbol table

Published Oct 7, 2025 · Updated Oct 7, 2025

Out-of-bounds read in the GNU Binutils 2.45 linker allows local users to crash ld by supplying an ELF file with an unsorted symbol table. bfd/elflink.c accepts a local symbol after global symbols when elf_bad_symtab is false, so get_link_hash_entry relies on invalid symbol ordering and reads beyond its hash-entry bounds. Exploitation requires the ability to make ld process the crafted object file; the documented consequence is a linker crash, not code execution or data modification.
