Subject: CVE request: Qemu: usb: ehci: memory leakage in ehci_init_transfer

   Hello,

Quick Emulator(Qemu) built with the USB EHCI Emulation support is vulnerable 
to a memory leakage issue. It could occur while processing packet data in 
'ehci_init_transfer'.

A guest user/process could use this issue to leak host memory, resulting in 
DoS for a host.
