Title: EDK II vulnerabilities
Summary: Several security issues were fixed in EDK II.
It was discovered that EDK II did not check the buffer length in XHCI,
which could lead to a stack overflow. A local attacker could potentially
use this issue to cause a denial of service. This issue only affected
Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2019-0161)
Laszlo Ersek discovered that EDK II incorrectly handled recursion. A
remote attacker could possibly use this issue to cause EDK II to consume
resources, leading to a denial of service. This issue only affected
Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2021-28210)
Satoshi Tanda discovered that EDK II incorrectly handled decompressing
certain images. A remote attacker could use this issue to cause EDK II to
crash, resulting in a denial of

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.
