Compliance Impact

The vulnerability allows remote code execution by bypassing sandbox protections, which can lead to unauthorized access and control over the affected system.

Such unauthorized access and potential data breaches could negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require strict controls over data security and protection against unauthorized access.

Failure to patch this vulnerability could result in violations of these regulations due to compromised confidentiality, integrity, and availability of sensitive data.
