System interruption via out-of-bounds driver read
Published Oct 8, 2024 · Updated Aug 19, 2026
Out-of-bounds read in the Windows Mobile Broadband Driver allows attackers to interrupt affected Windows systems. Microsoft identifies the driver as the affected component but has not published the specific routine, input, or unchecked read operation. Exploitation requires access to an adjacent network and can make the targeted system unavailable without reported data disclosure or modification.
