CVE-2025-7458: 
SQLite vulnerability analysis and mitigation

An integer overflow vulnerability (CVE-2025-7458) was discovered in SQLite versions 3.39.2 through 3.41.1. The vulnerability exists in the sqlite3KeyInfoFromExprList function and was disclosed on July 29, 2025 (NVD).

The vulnerability is an integer overflow condition in the sqlite3KeyInfoFromExprList function. It occurs when processing SELECT statements with a large number of expressions in the ORDER BY clause. The issue has been assigned a CVSS v3.1 base score of 9.1 CRITICAL and CVSS v4.0 score of 6.9 MEDIUM (NVD, Snyk).

When successfully exploited, this vulnerability can lead to denial of service conditions or disclosure of sensitive information from process memory. The attacker must have the ability to execute arbitrary SQL statements to exploit this vulnerability (NVD).

The vulnerability requires an attacker to have the ability to execute arbitrary SQL statements. Exploitation is achieved by crafting a SELECT statement with a large number of expressions in the ORDER BY clause (NVD).

A fix has been implemented in SQLite that correctly handles SELECT DISTINCT ... ORDER BY statements when all result set terms are constant and there are more result set terms than ORDER BY terms (SQLite Patch). Users should upgrade to a version newer than 3.41.1 to address this vulnerability.
