CVE-2025-32707 is an elevation-of-privilege vulnerability in the Windows NTFS file system caused by an out-of-bounds read condition. The issue is described as occurring in NTFS handling of specially crafted file metadata, including scenarios involving mounted virtual drives such as VHD files. By triggering NTFS to read beyond the bounds of an allocated memory buffer, a local attacker can disclose sensitive kernel memory contents and use that information to facilitate escalation to higher privileges, including SYSTEM. The vulnerability is rated Important with a CVSS score of 7.8 and has been reported as exploited in the wild.
