AI-suggested
1. Upgrade affected systems to a supported and patched version of Windows 10 or later, as Windows 10 Version 1507 is legacy and no patches are currently available for this version. 2. If Hyper-V is not required, disable the Hyper-V feature to reduce the attack surface. 3. Restrict local access to trusted users only, employing strict access controls and monitoring for unusual local activity. 4. Implement application whitelisting and endpoint detection and response (EDR) solutions to detect and prevent suspicious privilege escalation attempts. 5. Regularly audit and monitor system logs for signs of race condition exploitation or privilege escalation attempts. 6. Employ least privilege principles to limit the permissions of local users and services. 7. Prepare incident response plans specifically addressing privilege escalation scenarios. 8. Stay informed on Microsoft security advisories for updates or patches addressing this vulnerability and apply them promptly once available.
Description
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Hyper-V allows an authorized attacker to elevate privileges locally.
