CVE-2025-1864Network attack vector

Code execution via undersized continuation array

Published Mar 3, 2025 · Updated Mar 3, 2025

Buffer overflow in radareorg radare2 before 5.9.9 allows context-dependent attackers to crash the process or execute code via a crafted magic file. The __magic_file_check_mem function in libr/magic/funcs.c adds only 20 entries when a continuation level exceeds the allocated array, leaving high-index levels out of bounds. Processing attacker-controlled magic rules is the gate, and the resulting memory corruption allows a process crash or arbitrary code execution.
