CVE-2022-47021 Opusfile vulnerability
Title: Opusfile vulnerability
Summary: Opusfile could be made to crash if it received specially crafted input.
It was discovered that Opusfile was not properly validating pointer
arguments in some of its functions, which could lead to a NULL pointer
dereference. An attacker could possibly use this issue to cause a denial
of service or have other unspecified impacts.
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 publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update
