CVE-2023-5366 [HIGH] Open vSwitch vulnerabilities
Title: Open vSwitch vulnerabilities
Summary: Several security issues were fixed in Open vSwitch.
Timothy Redaelli and Haresh Khandelwal discovered that Open vSwitch
incorrectly handled certain crafted Geneve packets when hardware offloading
via the netlink path is enabled. A remote attacker could possibly use this
issue to cause Open vSwitch to crash, leading to a denial of service.
(CVE-2023-3966)
It was discovered that Open vSwitch incorrectly handled certain ICMPv6
Neighbor Advertisement packets. A remote attacker could possibly use this
issue to redirect traffic to arbitrary IP addresses. (CVE-2023-5366)
Instructions: This update uses a new upstream release, which includes additional bug
fixes. 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 publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
