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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CWE-362 The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.

Executive Summary

This vulnerability is a use-after-free issue in the Windows Speech Brokered API. It allows an authorized attacker to elevate their privileges locally on the affected system.

Impact Analysis

The vulnerability can lead to an elevation of privileges, meaning an attacker who already has some level of access can gain higher-level permissions. This can compromise the confidentiality, integrity, and availability of the system.

Mitigation Strategies

This vulnerability allows an authorized attacker to elevate privileges locally via a use after free in the Windows Speech Brokered API.

To mitigate this vulnerability, it is recommended to apply the security updates provided by Microsoft as soon as possible.

Compliance Impact

The vulnerability allows an authorized attacker to elevate privileges locally through a use after free in the Windows Speech Brokered API.

Such elevation of privilege vulnerabilities can potentially lead to unauthorized access or modification of sensitive data, which may impact compliance with standards and regulations like GDPR and HIPAA that require protection of personal and health information.

However, the provided information does not explicitly describe the direct effects on compliance with these standards.
