SQLite3 3.50.0 Integer Overflow DoS via setupLookaside
CVE-2025-52099 - October 24, 2025

SQLite FTS5 Integer Overflow Enables Out-of-Bounds Write
CVE-2025-7709 - September 08, 2025

An integer overflow exists in the FTS5 https://sqlite.org/fts5.html  extension. It occurs when the size of an array of tombstone pointers is calculated and truncated into a 32-bit integer. A pointer to partially controlled data can then be written out of bounds.

Integer Overflow or Wraparound

SQLite 3.39.2-3.41.1 Order By ExprList Integer Overflow
CVE-2025-7458 9.1 - Critical - July 29, 2025

An integer overflow in the sqlite3KeyInfoFromExprList function in SQLite versions 3.39.2 through 3.41.1 allows an attacker with the ability to execute arbitrary SQL statements to cause a denial of service or disclose sensitive information from process memory via a crafted SELECT statement with a large number of expressions in the ORDER BY clause.

SQLite Memory Corrupt: Aggregates > Columns Before 3.50.2
CVE-2025-6965 - July 15, 2025

There exists a vulnerability in SQLite versions before 3.50.2 where the number of aggregate terms could exceed the number of columns available. This could lead to a memory corruption issue. We recommend upgrading to version 3.50.2 or above.

Numeric Truncation Error

SQLite concat_ws() Integer Overflow Heap Buffer Overflow (CVE-2025-3277)
CVE-2025-3277 9.8 - Critical - April 14, 2025

An integer overflow can be triggered in SQLites `concat_ws()` 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.

Integer Overflow or Wraparound

SQLite 3.49.0/3.49.1 DoS via sqlite3_db_config arg
CVE-2025-29088 - April 10, 2025

In SQLite 3.49.0 before 3.49.1, certain argument values to sqlite3_db_config (in the C-language API) can cause a denial of service (application crash). An sz*nBig multiplication is not cast to a 64-bit integer, and consequently some memory allocations may be incorrect.

SQLite 3.44.0-3.49.0: concat_ws() Integer Overflow (before 3.49.1)
CVE-2025-29087 7.5 - High - April 07, 2025

In SQLite 3.44.0 through 3.49.0 before 3.49.1, the concat_ws() SQL function can cause memory to be written beyond the end of a malloc-allocated buffer. If the separator argument is attacker-controlled and has a large string (e.g., 2MB or more), an integer overflow occurs in calculating the size of the result buffer, and thus malloc may not allocate enough memory.

Integer Overflow or Wraparound

SQLite UAF in jsonParseAddNodeArray() Leads to Local DOS via Malicious Input

A Memory Leak vulnerability exists in SQLite Project SQLite3 3.35.1 and 3.37.0 via maliciously crafted SQL Queries (made via editing the Database File), it is possible to query a record, and leak subsequent bytes of memory
CVE-2021-45346 4.3 - Medium - February 14, 2022

A Memory Leak vulnerability exists in SQLite Project SQLite3 3.35.1 and 3.37.0 via maliciously crafted SQL Queries (made via editing the Database File), it is possible to query a record, and leak subsequent bytes of memory that extend beyond the record, which could let a malicious user obtain sensitive information. NOTE: The developer disputes this as a vulnerability stating that If you give SQLite a corrupted database file and submit a query against the database, it might read parts of the database that you did not intend or expect.

Memory Leak

A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0

A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally allowed to execute commands). This report does NOT imply any problem in the SQLite library.
