Unusually, this Windows kernel elevation of privilege flaw is scoped to the newest client branch only: Windows 11 Version 24H2 on x64 and ARM64. It is High Severity (CVSS 8.8) with a 61 percent EPSS probability. Bugs confined to a new release often live in freshly introduced code, so early 24H2 adopters carry exposure their 23H2 peers do not.
Do this: Update early-adopter Windows 11 24H2 devices, including the ARM64 laptops that pilot groups tend to run.
