QEMU: net: e1000: infinite loop while processing transmit descriptors

An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits tx descriptors in processtxdesc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial o...
