A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.
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.

use this to cause a denial of service (memory exhaustion). (CVE-2021-3669)
It was discovered that the KVM VMX implementation in the Linux kernel did
not properly handle indirect branch prediction isolation between L1 and L2

Please note that when USN 5975-1 was originally published, it incorrectly
included the linux-gcp kernel for Ubuntu 16.04 ESM. References to that
kernel have been removed from this USN and the correct information for it
has been published in USN 6007-1.
