A reachable assertion vulnerability was found in the USB EHCI emulation code of QEMU. This issue occurs while processing USB requests due to missed handling of DMA memory map failure. This flaw allows a malicious privileged user within the guest to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
