CVE-2026-50518 is a critical heap-based buffer overflow vulnerability in Windows DHCP Server. The flaw is triggered when the service processes specially crafted network requests containing malicious domain name data, leading to heap memory corruption. Because the vulnerable component is network-reachable and the issue is exploitable by an unauthorized attacker, successful exploitation can result in remote code execution without requiring prior authentication or user interaction.
