Local privilege escalation via out-of-bounds read
Published Mar 10, 2026 · Updated Mar 10, 2026
Out-of-bounds read in Windows NTFS allows local users with existing access to elevate privileges on affected Windows systems. Microsoft identifies NTFS as the locus but has not published the specific parser, buffer, or operation that reads beyond its bounds. Local low-privilege access is required; successful exploitation grants elevated control over the affected system, including access to protected data and operations.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
