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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
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.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue caused by a race condition in multiple locations. It allows remote code execution without requiring additional privileges or user interaction.

Impact Analysis

An attacker could exploit this to execute arbitrary code remotely on your system. This may lead to data breaches, system compromise, or unauthorized access to sensitive information.

Compliance Impact

This vulnerability could lead to remote code execution, which may result in unauthorized access to sensitive data. This could violate GDPR's data protection requirements and HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies

Apply the latest security patches or updates from the vendor as soon as they become available. Since this is a use-after-free issue with remote code execution potential, prioritize patching systems exposed to network traffic. Monitor vendor advisories for specific fixes related to the affected components.
