Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use after free issue in Windows LDAP. It allows an unauthorized attacker to execute arbitrary code remotely over a network by exploiting a memory corruption flaw in the LDAP protocol implementation.

Detection Guidance

Detection of CVE-2026-62795 requires monitoring for unusual LDAP-related activity or crashes. Check Windows Event Logs for LDAP service errors or application crashes. Use network monitoring tools to inspect LDAP traffic for anomalies. Microsoft may provide detection guidance in security updates or advisories.

Impact Analysis

An attacker could exploit this to run malicious code on your system, potentially taking control of it. This could lead to data theft, installation of malware, or disruption of services if the system is part of a network.

Compliance Impact

This vulnerability allows remote code execution via a use-after-free flaw in Windows LDAP, which could lead to unauthorized access or data breaches. Such breaches may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information, depending on the affected system and data involved.

Mitigation Strategies

Apply the latest security updates from Microsoft for Windows LDAP to patch the use-after-free vulnerability. Monitor Microsoft's update guide for patches and install them promptly.
