Exploitation Conditions

Exploitation requires local access to a host that has the Intel QuickAssist Adapter 8960 and its software (before version 1.13) installed, plus an already-authenticated, low-privileged local account (PR:L) able to interact with the adapter's Ring 3 user-application software; no user interaction and no special internal knowledge are needed (AC:L, AT:N, UI:N). Limiting factors that reduce realistic risk: the vector is strictly local (AV:L) - there is no remote/network path - and the attacker must already possess valid credentials and the presence of the specific 8960 adapter software, so systems without this niche accelerator hardware/software are not exposed at all.

Impact

Signals are consistent and point to a genuine but not urgent local-escalation issue. The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N) confirms local access with low attack complexity, low existing privileges, and no user interaction, with total (VC:H/VI:H/VA:H) impact on the vulnerable system and no subsequent-system impact - hence the elevated 8.5 score. However, EPSS is only 0.01% (3rd percentile) and CISA SSVC scores Exploitation as none and Automatable as no, while rating Technical Impact as total. The picture is coherent: high technical impact if exploited, but no evidence of active or automatable exploitation and no KEV listing. This is a patch-in-normal-cycle priority for organizations that actually deploy the 8960 adapter, not a drop-everything emergency; the local-only vector and required authentication meaningfully constrain real-world risk despite the high base score.

Exploit ScenarioDerived

A low-privileged but authenticated user already logged into a server that hosts the Intel QuickAssist Adapter 8960 crafts input that supplies a malicious pointer value to the adapter's Ring 3 user-application software, triggering the untrusted pointer dereference. Because attack complexity is low and no user interaction is needed, the attacker leverages the resulting memory corruption to escalate to higher privileges on the local system. No public proof-of-concept has been identified at time of analysis.

AnalysisAIv1 – Jul 23, 2026

Local privilege escalation in Intel QuickAssist Adapter 8960 software before version 1.13 allows an authenticated, low-privileged user to abuse an untrusted pointer dereference in a Ring 3 user-application component to gain elevated privileges on the host. The flaw yields total impact (high confidentiality, integrity, and availability) on the affected system and carries a CVSS 4.0 base score of 8.5. There is no public exploit identified at time of analysis, and EPSS rates near-term exploitation probability at just 0.01%.

RemediationAI

Vendor-released patch: update the Intel QuickAssist Adapter 8960 software to version 1.13 or later, per Intel advisory INTEL-SA-01387 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01387.html). Because exploitation requires an authenticated local user, effective compensating controls until patching is complete include restricting local and interactive login access to hosts equipped with the 8960 adapter to trusted administrators only, limiting which accounts can load or invoke the QAT user-space software, and monitoring for anomalous local process behavior around the adapter software - with the trade-off that these controls reduce but do not eliminate exposure and may constrain legitimate operators who rely on QAT-accelerated workloads. No standalone feature-disable workaround is published by Intel, so upgrading to 1.13 is the definitive fix.

Technical ContextAI · show details

Intel QuickAssist Technology (QAT) accelerates cryptographic and compression workloads via a dedicated PCIe hardware adapter (here the 8960) driven by host-side software and drivers. The root cause is CWE-822 (Untrusted Pointer Dereference), in which the software dereferences a pointer whose value originates from an untrusted source (e.g., user-controlled input crossing into the adapter software's Ring 3 user-application code) without adequate validation. Per the CPE (cpe:2.3:a:n/a:intel(r)_quickassist_adapter_8960_software:*), the affected component is the adapter software package rather than the silicon itself, and controlled corruption of a dereferenced pointer can steer execution or memory access to escalate privileges.

DescriptionCVE.org

Untrusted pointer dereference for some Intel(R) QuickAssist Adapter 8960 software before version 1.13 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable escalation of privilege. 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.

Executive ViewAI

Why It Matters

Intel QuickAssist Adapter 8960 versions before 1.13 contain a local privilege escalation vulnerability (CVSS 8.5) that allows standard system users to gain full administrative rights. This directly impacts organizations deploying QuickAssist for cryptographic acceleration-including payment processors, cloud providers, and secure communications infrastructure-by creating a complete system compromise pathway from low-privilege accounts. No patch is currently available, requiring immediate access restrictions to prevent insider exploitation or abuse of compromised standard accounts.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: restrict local system access to approved administrative and service accounts only; implement privileged access management (PAM) to control administrative functions; deploy endpoint detection and response (EDR) to detect local privilege escalation patterns; disable QuickAssist on systems where not operationally critical; isolate affected systems from sensitive network segments; establish enhanced audit logging of all local account activities and privilege changes.
