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.

CVE-2020-10756 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Ziming Zhang and VictorV discovered that the QEMU SLiRP networking
implementation incorrectly handled replying to certain ICMP echo requests.
An attacker inside a guest could possibly use this issue to leak host
memory to obtain sensitive information. This issue only affected Ubuntu
18.04 LTS. (CVE-2020-10756)
Eric Blake and Xueqiang Wei discovered that the QEMU NDB implementation
incorrectly handled certain requests. A remote attacker could possibly use
this issue to cause QEMU to crash, resulting in a denial of service. This
issue only affected Ubuntu 20.04 LTS. (CVE-2020-10761)
Ziming Zhang discovered that the QEMU SM501 graphics driver incorrectly

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing C

CVE-2020-16092 QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c
An assertion failure issue was found in the net_tx_pkt_add_raw_fragment() function in hw/net/net_tx_pkt.c. This assertion comes from the code that processes network packets. This code is shared between e1000e, vmxnet3 and apparently a few more devices. A malicious guest user/process could abuse this flaw to abort the QEMU process on the host, resulting in a denial of service condition.
