CVE-2026-85698Public exploit

Application crash via unchecked table-leaf cell count

Published Sep 4, 2026 · Updated Sep 4, 2026

An out-of-bounds read in Turso 0 through 0.8.0-pre.8 allows attackers to crash applications by querying a malicious database file. The table-leaf page reader's cell_table_leaf_read_rowid path trusts the page header's cell count, computes an unchecked cell-pointer offset, and indexes beyond the page buffer during a binary-search seek. The crash requires an application to open and query an attacker-supplied database; the demonstrated consequence is an unrecoverable Rust panic, not data disclosure or code execution.
