Exploitability

CWE

KEV

CWE ID	Description
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.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 race condition in the Windows Speech Brokered API where concurrent execution uses a shared resource without proper synchronization.

An authorized attacker can exploit this flaw to elevate their privileges locally on the affected system.

Impact Analysis

The vulnerability allows an attacker with some level of authorization to gain higher privileges on the local system.

This can lead to full control over the affected system, potentially compromising confidentiality, integrity, and availability of data and system resources.

Compliance Impact

This vulnerability allows an authorized attacker to elevate privileges locally by exploiting a race condition in the Windows Speech Brokered API.

Elevation of privileges can lead to unauthorized access or modification of sensitive data, which may impact compliance with standards and regulations such as GDPR and HIPAA that require strict controls on data confidentiality, integrity, and access.

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

Mitigation Strategies

This vulnerability allows an authorized attacker to elevate privileges locally due to a race condition in the Windows Speech Brokered API.

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

Additionally, limiting local user privileges and monitoring for unusual privilege escalation attempts can help reduce risk.
