Senserva AI Opinion for CVE-2025-29971
Web Threat Defense, WTD.sys, is a Windows 11 security driver, and this denial of service flaw in it is rated High Severity at CVSS 8.8 with a 58 percent exploit probability across Windows 11 22H2 and 23H2. A crashable kernel security driver is doubly interesting to attackers: the crash itself blue-screens the machine, and killing a defense component can be step one of a larger intrusion. The flaw is exclusive to the Windows 11 client line in this listing.
Do this: Push the update to Windows 11 22H2 and 23H2 endpoints and investigate any cluster of WTD.sys-attributed crashes as potentially hostile.
