CVE-2020-35498 Open vSwitch vulnerability
Title: Open vSwitch vulnerability
Summary: Open vSwitch could be made to crash or perform unexpectedly if it received
specially crafted network traffic.
Joakim Hindersson discovered that Open vSwitch incorrectly parsed certain
network packets. A remote attacker could use this issue to cause a denial
of service, or possibly alter packet classification.
Instructions: In general, a standard system update will make all the necessary changes.

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 publish
