CVE-2024-45383Public exploit

Local system crash via duplicate IRP completion

Published Sep 12, 2024 · Updated Sep 13, 2024

Improper resource control in Microsoft HD Audio Bus Driver 10.0.19041.3636 allows local users to crash Windows via a WMI request. HDAudBusWmiFunctionControl completes an HDAudBus_DMA IRP through WmiCompleteRequest, then HDAudBusWmiSystemControl calls IofCompleteRequest on the processed packet. A low-privileged application must open the DMA WMI block with event notifications enabled, causing bug check 0x44 and a system crash.
