September 2026 Patch Tuesday set an all-time record with 973 CVEs addressed across the Microsoft portfolio. We’re only four months into the Patch Apocalypse and everyone seems to be numb with respect to the insane number of CVEs reported. Despite this massive number, only two, CVE-2026-85880 and CVE-2026-81963, were reported Known Exploited and none were Publicly Disclosed. So for most of us, it’s still business as usual, patch systems at highest risk, but be prepared … More → The post October 2026 Patch Tuesday forecast: Time for an Office cleanup appeared first on Help Net Security .

CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation.   CVE-2026-75650 Adobe Commerce and Magento Improper Neutralization of Special Elements Used in a Template Engine Vulnerability CVE-2026-81963 Microsoft Windows Link Following Vulnerability   CVE-2026-85880 Microsoft Windows Heap-Based Buffer Overflow Vulnerability  CVE-2026-86218 N-able N-central Static Code Injection Vulnerability  These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based...

Microsoft released its monthly security updates on Tuesday, and one of the flaws it closed is already being used in attacks. The bug sits in a core Windows kernel driver that handles network socket operations. An attacker with code already running on a machine can use it to escalate to SYSTEM. That patch goes out first. The flaw is tracked as CVE-2026-68820 (CVSS score: 7.0) and is the only
