CVE-2025-1153Network attack vector

Linker crash via failed output-file setup

Published Feb 10, 2025 · Updated Apr 4, 2025

Memory corruption in bfd_set_format in GNU Binutils 2.43 and 2.44 allows attackers to crash ld via an unwritable output path. The linker reaches bfd_set_format after output-file creation fails and continues using the failed output state instead of stopping. Triggering the fault requires warning suppression, an output location that cannot be opened, and execution of ld; impact is limited to termination of that linker process.
