    Published: 30 Oct 2026Last Modified: 9 Nov 2026

    Summary: SQLite before 3.54.0 FTS5 Heap Buffer Overflow via fts5MergeRowidLists()

    Details: SQLite before 3.54.0 built with FTS5 contains a heap buffer overflow in fts5MergeRowidLists() that undersizes the output buffer when merging detail=none prefix doclists. Attackers who can populate a detail=none FTS5 table with negative rowids and run a prefix MATCH query can write past the allocation, corrupting heap memory and crashing the process.
