Microsoft fixes Windows 10's drive corrupting NTFS denial of service vulnerability In the middle of January, we reported about a vulnerability in Windows 10 that could be used to corrupt the contents of an NTFS formatted drive. A specially crafted folder name was all that was needed to cause a volume to be marked as dirty, and then require a fix with the Chkdsk utility. But Chkdsk did not always do the trick, leaving victims with unbootable systems. A couple of months ago, Microsoft started testing a fix with Windows Insiders and now the patch is being made available to everyone. It addresses the problems which was being tracked as CVE-2021-28312 (Windows NTFS Denial of Service Vulnerability).
