Description
CVE-2026-119373 is a heap buffer overflow vulnerability in SQLite versions before 3.54.0 when built with FTS5 enabled. The flaw occurs in the fts5MergeRowidLists() function, which undersizes the output buffer during merging of detail=none prefix doclists. An attacker able to insert negative rowids into a detail=none FTS5 table and execute a prefix MATCH query can trigger out-of-bounds writes, leading to heap corruption and process crashes.
