NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-block-ssh package and not the qemu-block-ssh package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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 net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c.
