CVE-2025-63744Public exploit

Process crash via unchecked dyldcache descriptor

Published Nov 14, 2025 · Updated Nov 16, 2025

NULL pointer dereference in radare2 6.0.5 and earlier allows context-dependent attackers to crash the program via a crafted file. The bin_dyldcache.c load() function dereferences the plugin field of the RIODesc returned by desc_get() without checking whether the descriptor is NULL. A user or automated analysis pipeline must process the crafted binary, after which the affected radare2 process terminates with a segmentation fault.
