D-Link — known exploited vulnerabilities
The CISA Known Exploited Vulnerabilities catalog (KEV) lists vulnerabilities that CISA has confirmed are being exploited in the wild; U.S. federal civilian agencies are required to remediate each entry by its due date. This page joins the KEV entries for D-Link with NVD CVSS scores and CISA's ransomware-campaign flag. See our methodology or browse all CVEs.
