Microsoft and Adobe Patch Tuesday, February 2026 Security Update Review

Microsoft’s February 2026 Patch Tuesday and accompanying Adobe advisories address dozens of flaws—61 Microsoft vulnerabilities (including multiple critical and six zero-days exploited in the wild) and 44 Adobe vulnerabilities—affecting components such as Desktop Window Manager, Remote Desktop Services, Windows Shell, MSHTML, Remote Access Connection Manager, Office, and various Azure services; CISA has added several of the actively exploited issues to its Known Exploited Vulnerabilities catalog and is urging organizations to patch before March 3, 2026. The bulletin describes impacts (SYSTEM privilege escalation, RCE, DoS), provides product coverage and remediation guidance, and promotes Qualys tools and webinars to help prioritize and deploy patches.
