CVE-2026-69830
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk41th percentile - higher than 41% of all known CVEs
Summary
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows DHCP Server allows an unauthorized attacker to execute code over a network.
Risk Assessment
A remote attacker could exploit this vulnerability to execute code in the context of the DHCP server, potentially leading to control over the service and network.
Recommendation
Install the latest security patches for the DHCP server and restrict access to the service from trusted networks.
