CVE-2026-119591

SQLite before 3.54.0 contains a stack exhaustion vulnerability in countOfViewOptimization() that allows attackers to crash the host process via count() over a large multi-row VALUES clause. Attackers supplying SQL or a database file with a crafted view can trigger deeply nested TKPLUS expressions whose recursive freeing in sqlite3ExprDeleteNN() exhausts the C stack, causing denial of service.
