Microsoft's October Patch Tuesday, released on October 13, 2026, is the largest in the company's history. Cisco Talos counted 1,415 vulnerabilities addressed across Microsoft products, including 85 rated critical, 67 of them remote code execution flaws. Computer Weekly noted that the total exceeds the number Microsoft fixed in all of 2023, and that it shatters the previous record of roughly 1,000 flaws set just last month, which itself had passed a mark of a little over 600 set in July. By comparison, the October 2025 release addressed about 175 flaws.
