CVE-2025-43380

Code execution via ICC profile buffer overwrite

Published Nov 4, 2025 · Updated Nov 4, 2025

Out-of-bounds write in sips in Apple macOS allows remote attackers to execute code by opening a crafted ICC profile. The ICC profile parser fails to validate user-supplied profile data before writing it past the end of an allocated buffer. A target must visit a malicious page or open a malicious file; successful exploitation runs code in the current process, while Apple reports app termination.
