In NTFS-3G versions 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-2021-35266 [HIGH] CWE-119 ntfs-3g: Heap buffer overflow triggered by a specially crafted NTFS inode pathname
ntfs-3g: Heap buffer overflow triggered by a specially crafted NTFS inode pathname
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution.
The ntfs3g package is susceptible to a heap overflow on crafted input. When processing an NTFS inode pathname, proper bounds checking was not enforced leading to this software flaw. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
