Use-after-free memory corruption in Windows Autopilot on Windows 11 (24H2 and 25H2) enables a locally authenticated, low-privileged user to escalate privileges, achieving full confidentiality, integrity, and availability impact (C:H/I:H/A:H). The attack requires local access and high complexity (AV:L/AC:H/PR:L), meaning an attacker must meet specific memory state or race conditions - reducing opportunistic risk but not eliminating it for determined local threat actors. A vendor patch is available via MSRC; no public exploit code or CISA KEV listing has been identified at time of analysis.
