CVE-2023-42909

Code execution via malformed file processing

Published Dec 12, 2023 · Updated Nov 4, 2025

Memory corruption in AppleGraphicsControl in Apple macOS before 14.2 allows attackers to execute code by processing a malicious file. Apple identifies multiple memory-corruption defects and inadequate input validation, but does not disclose the parser, memory operation, or file format involved. Exploitation requires a user or application to process a maliciously crafted file and can terminate the affected application or execute attacker-controlled code in its context.
