Attack-Flow Graph

Executive Summary

This vulnerability is a buffer over-read in the Windows Kernel Memory. It allows an authorized attacker to read more data than intended from memory, which can lead to the disclosure of sensitive information locally on the affected system.

Compliance Impact

This vulnerability allows an authorized attacker to locally disclose information due to a buffer over-read in Windows Kernel Memory.

Information disclosure vulnerabilities can impact compliance with data protection regulations such as GDPR and HIPAA, as unauthorized access to sensitive information may violate requirements for data confidentiality and protection.

Organizations using affected Windows Kernel versions should assess the risk of information exposure and apply necessary patches to maintain compliance with these standards.

Impact Analysis

The impact of this vulnerability is information disclosure. An authorized attacker with local access could exploit this buffer over-read to gain access to sensitive information stored in kernel memory, potentially compromising confidentiality.
