Summary

CVE-2025-48816 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Microsoft Windows Server 2008. 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 29th 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 SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability CVE-2025-48816 is an integer overflow or wraparound in the HID class driver, accompanied by an out-of-bounds read condition. It carries a CVSS 3.1 base score of 7.8 and is tracked under CWE-190 and CWE-125. The affected component is the HID class driver, with the sole reference pointing to a Microsoft security advisory.

An attacker who already possesses local authorized access can exploit the flaw without user interaction to elevate privileges on the target system. Successful exploitation grants the attacker high impact across confidentiality, integrity, and availability.

The EPSS score remains flat at 0.0112 with no material increase after disclosure. The referenced Microsoft advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-48816 is the primary source for any available patches or mitigation guidance.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.

Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.

Process isolation confines the effects of an out-of-bounds read to the compromised process.

Input validation rejects malformed indices or lengths that would otherwise cause reads outside buffer bounds.

finds

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.

A.8.15 Logging partial match
finds

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.

prevents

Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.

prevents

Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.

prevents

Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
