CVE-2020-25625 log

Severity Medium
Remote No
Type Denial of service
An infinite loop issue was found in the USB OHCI controller emulator of QEMU before version 5.2.0. It could occur while servicing OHCI isochronous transfer descriptors (TD) in ohci_service_iso_td routine, as it retires a TD if it has passed its time frame. While doing so it does not check if the TD was already processed ones and holds an error code in TD_CC. It may happen if the TD list has a loop.

A guest user/process may use this flaw to consume cpu cycles on the host resulting in a DoS scenario.
