CVE-2026-11822

A flaw was found in SQLite's FTS5 full-text search extension. This vulnerability involves memory corruption, specifically an out-of-bounds read and a heap buffer overflow, which can be triggered by supplying a crafted database with malformed FTS5 page data. When an FTS5 MATCH query is executed against such a database, an attacker can cause process crashes, memory exhaustion, or achieve arbitrary code execution, potentially compromising the system.

Important: This flaw in the SQLite FTS5 full-text search extension can lead to arbitrary code execution or denial of service. Exploitation requires an application to process a specially crafted SQLite database containing malformed FTS5 page data, which could occur if an attacker provides a malicious database to a vulnerable application. This risk is elevated in scenarios where applications handle untrusted SQLite database files.
