CVE-2024-31636Public exploit

Process-memory disclosure via uninitialized name pointer

Published May 3, 2024 · Updated Jul 9, 2026

Information disclosure in LIEF before 0.15.0 allows local users to read process memory through the C Mach-O reader's name field. The Macho_Binary_t structure's name pointer is never initialized, yet macho_reader.c passes it to fprintf as a C string. Exploitation requires local execution and user interaction; the read can expose arbitrary process memory, while invalid pointers can crash the consuming process.
