This is a remote code execution bug in the Windows Mobile Broadband Driver, the component handling cellular modem connections, on Windows 10 21H2 across 32-bit, ARM64, and x64 builds. Mobile broadband RCE bugs matter most for laptops and tablets with built-in cellular modems, a smaller but real slice of the fleet.
Do this: Patch laptops and devices with cellular modems running Windows 10 21H2; desktops without mobile broadband hardware carry less practical exposure.
