Improper input validation for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of 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 (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AnalysisAI
Improper input validation in Intel Quick Assist Technology (QAT) software drivers for Windows prior to version 1.13 allows a local authenticated user to trigger a denial of service condition. The flaw resides in the Ring 3 (user-space application) layer of the driver stack, meaning an unprivileged but authenticated local adversary can cause high availability impact - potentially crashing the driver or the system - with minor confidentiality and integrity side effects. No public exploit code has been identified at time of analysis, EPSS sits at 0.02% (6th percentile), and CISA SSVC classifies exploitation as none and the attack as non-automatable, indicating negligible current threat activity.
Technical ContextAI
Intel Quick Assist Technology (QAT) is a hardware-accelerated offload engine for cryptographic operations and data compression, typically deployed in enterprise servers and data center infrastructure running Windows. The affected component is the user-space driver interface (Ring 3), which bridges application-level requests to the underlying QAT hardware. CWE-20 (Improper Input Validation) indicates that the driver fails to adequately sanitize or validate data supplied by user-space applications before processing it, allowing a crafted input to push the driver into an undefined or faulting state. The CPE string 'cpe:2.3:a:n/a:intel(r)_qat_software_drivers_for_windows' confirms only the Windows driver package is in scope; Linux QAT drivers are not referenced. The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L) confirms local, low-complexity access with no special attack requirements beyond a standard authenticated session.
RemediationAI
The primary remediation is to upgrade to Intel QAT software drivers for Windows version 1.13 or later, as confirmed by Intel Security Advisory INTEL-SA-01387 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01387.html). Organizations should consult the advisory directly for the download link, as CPE data does not specify a patch distribution URL. Where immediate patching is not feasible, compensating controls should focus on restricting local access: limit which user accounts can interact with QAT-enabled processes or services, enforce least-privilege principles so only necessary service accounts hold local logon rights on QAT-equipped systems, and monitor for anomalous local process activity targeting QAT interfaces. In high-availability environments relying on QAT for cryptographic offload or compression, consider redundant processing paths that can tolerate a QAT driver fault without cascading service disruption. Note that these workarounds do not eliminate the vulnerability - only the version 1.13 upgrade resolves the underlying input validation defect.
