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.

CVE-2022-36763 [HIGH] CWE-680 EDK2: heap buffer overflow in Tcg2MeasureGptTable()
EDK2: heap buffer overflow in Tcg2MeasureGptTable()
EDK2 is susceptible to a vulnerability in the Tcg2MeasureGptTable() function, allowing a user to trigger a heap buffer overflow via a local network. Successful exploitation of this vulnerability may result in a compromise of confidentiality, integrity, and/or availability.
A heap buffer overflow flaw was found via the Tcg2MeasureGptTable() function in EDK2, arising from inadequate validation of the GPT Primary Header, presenting a minor risk to confidentiality and integrity. The primary consequence is likely a crash or denial of service. This issue may allow a local attacker to craft a GPT table, causing an integer overflow and consequent buffer overflow.
Statement: Red Hat has protection mechanisms in place against buffer overflows, s
