CVE-2025-1180Public exploitNetwork attack vector

Linker crash via invalid EH-frame read

Published Feb 11, 2025 · Updated Feb 11, 2025

Memory corruption in GNU Binutils ld 2.43 allows remote attackers to crash the linker with a crafted ELF input file. _bfd_elf_write_section_eh_frame reads an invalid address while processing the file with --gc-sections and --gc-keep-exported. Exploitation requires a user or build system to invoke ld with both options on the attacker-supplied file, and the demonstrated consequence is a linker crash.
