Intel Quick Assist Technology Denial-of-Service Vulnerability

Vulnerability

A denial-of-service vulnerability has been identified in Intel Quick Assist Technology (QAT) on certain Intel platforms. The issue arises from improper authorization within the kernel, which may allow an unprivileged, authenticated user to disrupt system availability. This vulnerability can potentially be exploited locally, without user interaction, and does not require special internal knowledge. The flaw impacts the availability of the affected system, leading to significant disruptions.

Impact

Exploitation of this vulnerability can cause a denial-of-service condition, disrupting normal system operations and availability.

Remediation

Users are advised to follow existing security best practices and implement alternate security controls. All guest operating systems or applications using Intel QAT should be trusted, or steps should be taken to ensure that untrusted applications or guests cannot send incorrectly formatted requests.
