CVE-2024-54568Network attack vector

Application crash via unchecked ATS buffer copy

Published Aug 29, 2025 · Updated Apr 2, 2026

Buffer overflow in ATS in Apple macOS Sequoia before 15.2 allows remote attackers to terminate an application via a crafted file. ATS copies attacker-controlled file data into a buffer without checking that the destination is large enough, causing the parsing application to terminate. User interaction is required to open or otherwise process the file, and no confidentiality or integrity impact is published.
