CVE-2025-3277

An integer overflow can be triggered in SQLite’s function.

Published Apr 14, 2025 · updated Oct 15, 2026 · sqlite sqlite

An integer overflow can be triggered in SQLite’s function. The resulting, truncated integer is then used to allocate a buffer. When SQLite then writes the resulting string to the buffer, it uses the original, untruncated size and thus a wild Heap Buffer overflow of size ~4GB can be triggered. This can result in arbitrary code execution.
