Microsoft Patch Tuesday for May 2026 — Snort rules and prominent vulnerabilities

Microsoft's May 2026 security update discloses 137 vulnerabilities (31 critical) affecting Windows, Office, Azure, and other components — including multiple remote code execution and elevation-of-privilege flaws (e.g., Netlogon, DNS Client, Win32K, Office/Word, Azure Managed Instance for Cassandra). Microsoft reports no observed in-the-wild exploitation; Talos published Snort and firewall rule coverage to detect attempts and advises applying patches and updating detection signatures.
