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.

ntfs-3g: Stack buffer overflow triggered when correcting differences between MFT and MFTMirror sections
NTFS-3G versions < 2021.8.22, a stack buffer overflow can occur when correcting differences in the MFT and MFTMirror allowing for code execution or escalation of privileges when setuid-root.
The ntfs3g package is susceptible to a stack overflow. When correcting differences between the MFT and MFTMirror, incorrect checks lead to possible code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
