What changed

The Cybersecurity and Infrastructure Security Agency (CISA) has updated its Known Exploited Vulnerabilities (KEV) Catalog by adding two new vulnerabilities: CVE-2026-3909 (Google Skia Out-of-Bounds Write Vulnerability) and CVE-2026-3910 (Google Chromium V8 Unspecified Vulnerability). These additions are based on evidence of active exploitation and are considered significant risks to the federal enterprise.

Federal Civilian Executive Branch (FCEB) agencies are mandated by Binding Operational Directive (BOD) 22-01 to remediate these identified vulnerabilities by the established due date to protect their networks. While BOD 22-01 specifically applies to FCEB agencies, CISA strongly recommends that all organizations prioritize the remediation of vulnerabilities listed in the KEV Catalog as part of their ongoing vulnerability management practices to mitigate cyberattack risks.

What to do next

FCEB agencies must remediate CVE-2026-3909 and CVE-2026-3910 by the due date specified in BOD 22-01.
All organizations are strongly urged to prioritize remediation of these vulnerabilities as part of their vulnerability management program.

Alert

CISA Adds Two Known Exploited Vulnerabilities to Catalog

Release Date

March 13, 2026

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

CVE-2026-3909 Google Skia Out-of-Bounds Write Vulnerability
CVE-2026-3910 Google Chromium V8 Unspecified Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
