Subject: CVE Request Qemu: usb: xhci memory leakage during device unplug
Hello,
Quick Emulator(Qemu) built with the USB xHCI controller emulation support is
vulnerable to a memory leakage issue. It could occur while doing a USB device
unplug operation; Doing so repeatedly would result in leaking host memory,
affecting other services on the host.
A privileged user inside guest could use this flaw to cause a DoS on the host
and/or potentially crash the Qemu process instance on the host.
