CISA Adds Two Known Exploited Vulnerabilities to Catalog

CISA has added two critical vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2026-3909 affecting Google Skia (out-of-bounds write) and CVE-2026-3910 affecting Google Chromium V8 (unspecified vulnerability). Both vulnerabilities have evidence of active exploitation in the wild, making them significant threats to federal and private sector organizations. These browser and graphics engine vulnerabilities are frequently targeted by threat actors as initial access vectors. Federal Civilian Executive Branch agencies are required to remediate these vulnerabilities per BOD 22-01 deadlines. CISA strongly advises all organizations to prioritize immediate patching of these vulnerabilities as part of their vulnerability management programs to reduce exposure to potential cyberattacks.

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 .
