Vulnerability Data

Out-of-bounds write for some Intel(R) QAT Windows software before version 2.6.0. within Ring 3: User Applications may allow an escalation of privilege. System software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege.…

more

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 (high), integrity (high) 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

Memory Protection directly mitigates out-of-bounds writes (CWE-787) by enforcing bounds checking and preventing unauthorized memory modification in the QAT user-mode component.

prevent

Process Isolation confines the Ring-3 QAT application, blocking the out-of-bounds write from escalating privileges into kernel or other address spaces.

prevent

Least Privilege restricts the authenticated user's initial rights, reducing the impact and feasibility of the high-complexity local privilege-escalation path.

PR.PS-06 mostly match
prevents

Secure-development practices (static analysis, bounds checking, code review) are the primary means of preventing out-of-bounds writes.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

detects

Security testing in development and acceptance can detect and prevent out-of-bounds write defects.

prevents

Secure development life cycle mandates practices that prevent out-of-bounds writes.

prevents

Application security requirements can specify bounds-checking and safe memory handling.

prevents

Secure architecture and engineering principles reduce the likelihood of buffer overflows.

prevents

Secure coding directly addresses out-of-bounds writes through language choice and coding standards.

prevents

Change management can enforce review gates that catch unsafe memory operations before deployment.
