The risk applies to both standard and Server Core installations. No specific sub-version constraints are listed beyond the major editions enumerated.", "description_and_impact": "The vulnerability is a race condition in the Windows SSDP Service that allows a local attacker who has authorized access to execute code with elevated privileges. Because the service does not properly synchronize concurrent operations on a shared resource, an attacker can trigger a timing attack to alter privilege escalation paths. The attack can result in the attacker gaining administrative rights on the affected machine, potentially enabling full system compromise.", "risk_and_exploitability": "The CVSS base score is 7 (High), indicating a strong severity, but the EPSS score is not available, so the current probability of exploitation is unknown. The vulnerability is not listed in CISA\u2019s Known Exploited Vulnerabilities catalog. The likely attack vector is local; an attacker with user-level access can trigger the race condition by sending crafted SSDP requests, which may require privilege escalation scripts or specialized tools. The exploit path depends on the attacker\u2019s ability to send concurrent requests to the SSDP service while ensuring the race condition occurs."}}}}, "created": "2026-04-15T15:15:06.637333+00:00", "updated": "2026-04-15T15:15:06.637343+00:00", "vendors": []}
