In SQLite 3.27.2, interleaving reads and writes in a single transaction with an fts5 virtual table will lead to a NULL Pointer Dereference in fts5ChunkIterate in sqlite3.c. This is related to ext/fts5/fts5_hash.c and ext/fts5/fts5_index.c.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
