CVE-2022-0419

Process crash via null object dereference

Published Feb 1, 2022 · Updated Aug 2, 2024

NULL pointer dereference in radare2 before 5.6.0 allows attackers to crash the process by supplying a crafted XNU kernelcache binary. The load_buffer function in libr/bin/p/bin_xnu_kernelcache.c enters its failure path and writes cache_buf through an obj pointer that can be null. The target must process the crafted binary; the resulting dereference terminates that radare2 process without demonstrated code execution.
