CVE-2025-69650Network attack vector

Utility crash via uninitialized relocation pointer free

Published Mar 6, 2026 · Updated Mar 6, 2026

Double free in GNU Binutils readelf development snapshots allows attackers to crash the utility with an ELF file containing malformed GOT relocations. dump_relocations can return before initializing all_relocations, after which process_got_section_contents() passes an uninitialized r_symbol pointer to free(), triggering SIGABRT. Exploitation requires readelf to process the crafted file; third parties dispute the CVE because the faulty code reportedly existed only in pre-release code leading to 2.46, and no code execution was observed.
