service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires applying the vendor patch that eliminates the null-pointer dereference in the QAT driver before version 2.6.0.

prevent

Enforces runtime memory protections that can detect or block invalid pointer dereferences before they produce a DoS in user-mode Ring 3 code.

prevent

Requires process isolation so that a crash in the vulnerable QAT application cannot affect other system components or availability.

detects

Security testing can detect NULL dereference defects before release.

prevents

Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.

prevents

Application security requirements can specify input validation and pointer-safety rules.

prevents

Secure architecture principles encourage defensive design that avoids unsafe pointer use.

prevents

Secure coding standards directly require NULL-pointer checks and safe dereference patterns.
