Doc Text:
A flaw was found in SQLite. A heap-based buffer overflow exists in the Full-Text Search 5 (FTS5) extension during the merging of prefix document lists. An attacker capable of inserting negative row identifiers into a configured table and executing a prefix search query can cause data to be written beyond allocated memory. This issue can lead to memory corruption, resulting in application crashes, a Denial of Service (DoS), or potentially arbitrary code execution.

Description OSIDB Bzimport 2026-10-30 12:09:21 UTC
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.
