CVE-2026-40427

Quick assessment

Affected
n/a Intel(R) QuickAssist Technology Driver for Windows
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Windows 环境下,部分 Intel(R) QuickAssist 技术驱动程序存在 Ring 3 层(用户模式)的“释放后使用”(Use-after-free)漏洞。该漏洞可能允许用户应用程序引发拒绝服务(DoS)攻击。具备已认证用户身份的未授权软件攻击者,结合低复杂度的攻击手段,即可触发拒绝服务。在无需特殊内部知识且无需用户交互的情况下,攻击者通过本地访问即可利用该漏洞。该潜在漏洞可能对受影响系统的机密性(无影响)、完整性(低影响)和可用性(高影响)造成影响,但不会导致系统后续出现机密性、完整性或可用性

Vulnerability Description
Use after free for some Intel(R) QuickAssist Technology Driver for Windows 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 (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
