CVE-2026-11822 is a memory-corruption vulnerability in SQLite versions before 3.53.2 affecting the FTS5 full-text-search extension. A malicious SQLite database containing malformed FTS5 page data can trigger an out-of-bounds read in fts5LeafSeek() through an attacker-controlled loop bound. Crafted continuation-page data can also cause an integer underflow in fts5ChunkIterate(), resulting in a heap-based buffer overflow write. The vulnerable parsing paths are reached when an FTS5 MATCH query is executed against the attacker-controlled database.
