Description

An infinite loop flaw was found in the e1000e NIC emulation code of QEMU. This issue occurs in the e1000e_write_packet_to_guest() routine while processing bogus RX descriptor data transmitted by the guest. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service.
