CVE-2022-47011Public exploit

Process crash via STABS parser memory leak

Published Aug 22, 2023 · Updated Oct 3, 2024

Memory leak in parse_stab_struct_fields in GNU Binutils 2.34 through 2.38 allows local users to crash a process via crafted STABS data. The function leaks memory while parsing STABS structure-field records from an input binary; public sources do not identify the unreleased allocation or branch. Repeated processing of attacker-supplied files is required to exhaust memory and crash the invoking Binutils process; no confidentiality or integrity impact is reported.
