Description Wolfgang Frisch 2020-09-17 13:04:55 UTC 
CVE-2020-25084

A use-after-free issue was found in USB(xHCI/eHCI) controller emulators of QEMU. It occurs while setting up USB packet, as usb_packet_map() routine may return an error, which was not checked. A guest user/process may use this flaw to crash the QEMU process resulting in DoS scenario.
