CVE-2025-24188Network attack vector

Browser crash via undisclosed logic error

Published Jul 29, 2025 · Updated Apr 2, 2026

Logic error in Apple Safari before 18.6 and macOS Sequoia before 15.6 allows remote attackers to crash Safari via crafted web content. Apple identifies the locus only as Safari logic and has not disclosed the affected function or the check that mishandles input. Successful triggering requires Safari to process attacker-controlled web content with user interaction, and the documented consequence is limited to an unexpected browser crash.
