Microsoft has released its October 2026 Patch Tuesday security updates, addressing vulnerabilities across its products and services. As organizations continue to navigate an evolving threat landscape, applying security patches promptly remains critical to reducing exposure and strengthening security posture. This month’s updates highlight the importance of identifying affected assets, prioritizing remediation, and staying ahead of emerging risks.
This Patch Tuesday is Microsoft’s largest security update ever, marking a significant increase over other recent massive releases, including the 400 security fixes in August and over 970 in September.
This month’s release addresses 1414 vulnerabilities, including 78 critical and 1329 important-severity vulnerabilities.
In this month’s updates, Microsoft has addressed two vulnerabilities, one of which has been exploited in the wild.
This month’s release includes fixes for several vulnerabilities that could potentially enable remote code execution, privilege escalation, or denial-of-service attacks. As always, timely patch deployment is crucial to reduce exposure and ensure systems remain resilient against exploitation attempts.
InstaScan delivers detections within 60 minutes. After October’s Patch Tuesday, Agent Insta customers had them within 5 minutes.
The October 2026 Microsoft vulnerabilities are classified as follows:

Discover and Prioritize Vulnerabilities in Vulnerability Management, Detection & Response (VMDR)
Qualys VMDR automatically detects new Patch Tuesday vulnerabilities using continuous updates to its Knowledgebase (KB).
You can see all your impacted hosts by these vulnerabilities using the following QQL query:
vulnerabilities.vulnerability: ( qid: 110538 or qid: 110539 or qid: 388977 or qid: 388978 or qid: 50152 or qid: 92473 or qid: 92474 or qid: 92475 or qid: 92476 or qid: 92477 or qid: 92478 or qid: 92479 or qid: 92480 or qid: 92481 or qid: 92482 or qid: 92483 or qid: 92484 or qid: 92485 or qid: 92486 or qid: 92487 or qid: 92488 or qid: 92489 or qid: 92490 or qid: 92491 or qid: 92492 or qid: 92493 or qid: 92494 or qid: 92495 )
Rapid Response with TruRisk™ Eliminate
Patch to the Latest Version
VMDR rapidly remediates Windows hosts by deploying the most relevant and applicable per-technology version patches. You can simply select the respective QIDs in the Patch Catalog and filter for “Missing” patches to identify and deploy the applicable, available patches with one click.
The following QQL will return the missing patches for this Patch Tuesday:
( qid: 110538 or qid: 110539 or qid: 388977 or qid: 388978 or qid: 50152 or qid: 92473 or qid: 92474 or qid: 92475 or qid: 92476 or qid: 92477 or qid: 92478 or qid: 92479 or qid: 92480 or qid: 92481 or qid: 92482 or qid: 92483 or qid: 92484 or qid: 92485 or qid: 92486 or qid: 92487 or qid: 92488 or qid: 92489 or qid: 92490 or qid: 92491 or qid: 92492 or qid: 92493 or qid: 92494 or qid: 92495 )
