|Type||Denial of service|
A reachable assertion issue was found in the USB EHCI emulation code of QEMU before version 5.2.0. It could occur while processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service.
