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.

In the Linux kernel, the following vulnerability has been resolved:
KEYS: trusted: Fix memory leak in tpm2_key_encode()
'scratch' is never freed. Fix this by calling kfree() in the success, and
in the error case.
in linux kernel, tpm2_key_encode() has a memory leak due to 'scratch' never being freed. This can lead to denial of service.
