Application crash via WindowServer type confusion

Published Mar 31, 2025 · Updated Jul 8, 2026

Type confusion in WindowServer in Apple macOS Ventura, Sonoma, and Sequoia allows attackers to terminate an application unexpectedly. WindowServer treats an unspecified object as the wrong type, but Apple has not disclosed the affected code path or malformed input that bypasses its checks. Apple has not disclosed the triggering input or access prerequisite, and the documented consequence is limited to an application crash.
