CVE-2026-11822
Full vulnerability record from the local CVENow database.
Description
SQLite before 3.53.2 contains an out-of-bounds read vulnerability in the FTS5 full-text search extension that allows attackers to crash the process by supplying a crafted database with a malformed FTS5 leaf page. Attackers can set an oversized term length in the leaf page so that fts5LeafSeek() reads past the end of the page buffer while comparing terms during an FTS5 MATCH query, in applications compiled with SQLITE_ENABLE_FTS5.

"value": "SQLite anterior a 3.53.2 contiene vulnerabilidades de corrupción de memoria en la extensión de búsqueda de texto completo FTS5 que permiten a los atacantes causar caídas de proceso, agotamiento de memoria o ejecución de código arbitrario al proporcionar una base de datos manipulada con datos de página FTS5 malformados. Los atacantes pueden desencadenar una lectura fuera de límites en fts5LeafSeek() a través de un límite de bucle controlado por el atacante y una escritura de desbordamiento de búfer de pila en fts5ChunkIterate() a través de una página de continuación manipulada que causa un desbordamiento negativo de enteros, explotable cuando se ejecuta una consulta FTS5 MATCH contra la base de datos maliciosa."
