CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2015-3246 Red Hat Libuser Race Condition Vulnerability CVE-2015-5287 Red Hat Automatic Bug Reporting Tool Privilege Escalation Vulnerability CVE-2019-1068 Microsoft SQL Server Remote Code Execution Vulnerability CVE-2021-23758 Ajax.NET Professional Deserialization of Untrusted Data Vulnerability CVE-2022-0995 Linux Kernel Out-of-Bounds Write Vulnerability CVE-2026-8452 Citrix NetScaler ADC and NetScaler Gateway Improper Restriction of Operations within the Bounds of a Memory Buffer 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 ac...
