CVE-2026-95882

Summary

A stack-based buffer overflow (CWE-121) exists in Windows Microsoft DirectMusic, allowing remote code execution without authentication over the network. This flaw enables an unauthenticated attacker to potentially take full control of affected systems.

Exploitability

Exploitation is highly likely due to the CVSS score of 9.8 and lack of authentication or user interaction requirements; however, no public exploit code or technical details are available.

Blast radius

If exploited, attackers could gain full system compromise on vulnerable Windows hosts with DirectMusic enabled, potentially leading to lateral movement, data theft, or ransomware deployment across the network.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Microsoft has not published a fixed version or patch level for CVE-2026-95882; disable the affected Microsoft DirectMusic component via Group Policy or registry settings as recommended in Microsoft Security Advisory ADV26XXXX (if available), or restrict network access to ports/services using DirectMusic.
