The ehci_advance_state function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular split isochronous transfer descriptor (siTD) list, a related issue to CVE-2015-8558.

CVE-2015-3209 [HIGH] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Matt Tait discovered that QEMU incorrectly handled the virtual PCNET
driver. A malicious guest could use this issue to cause a denial of
service, or possibly execute arbitrary code on the host as the user running
the QEMU process. In the default installation, when QEMU is used with
libvirt, attackers would be isolated by the libvirt AppArmor profile.
(CVE-2015-3209)
Kurt Seifried discovered that QEMU incorrectly handled certain temporary
files. A local attacker could use this issue to cause a denial of service.

Jan Beulich discovered that the QEMU Xen code incorrectly restricted write
access to the host MSI message data field. A malicious guest could use this

CVE-2016-4037 Qemu: usb: Infinite loop vulnerability in usb_ehci using siTD process
Qemu emulator built with the USB EHCI emulation support is vulnerable to an
infinite loop issue. It occurs during communication between host controller interface(EHCI) and a respective device driver. These two communicate via a split isochronous transfer descriptor list(siTD) and an infinite loop unfolds if there is a closed loop in this list.
A privileges used inside guest could use this flaw to consume excessive CPU cycles & resources on the host.
This issue is similar to CVE-2015-8558, but using siTD instead of iTD.
