Summary

CVE-2025-62467 is a high-severity Buffer Over-read (CWE-126) vulnerability in Microsoft Windows 10 1809. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 30th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces input validation and bounds checking that blocks the integer overflow/wraparound (CWE-190) exploited in the Projected File System driver.

prevent

Requires timely application of vendor patches that remediate the integer overflow flaw in Windows Projected File System before local exploitation can succeed.

prevent

Limits the initial privileges of an authorized local attacker, reducing the ability to trigger or benefit from the resulting privilege escalation.

Security testing in development can detect buffer over-reads before release.

prevents

Secure SDLC mandates input validation and bounds checking that can prevent buffer over-reads.

prevents

Application security requirements can specify buffer-size and bounds-checking rules.

prevents

Secure architecture principles include memory-safety and bounds-checking design choices.

prevents

Secure coding standards directly require bounds-checked buffer access, mitigating over-reads.
