An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
