CVE-2026-96134 · Severity: high · CVSS 7.5 · Published 2026-11-10

Windows DHCP Server, which assigns network addresses to devices on corporate networks, can be forced to consume excessive resources by an attacker sending malicious network traffic. An attacker can exploit this to knock the DHCP service offline, preventing devices from obtaining network connectivity and causing a denial of service.
