Summary

[none]

Details

In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in nettxpktaddrawfragment in hw/net/nettx_pkt.c.
