CVE-2026-42056
Quick assessment
Affected
n/a Intel(R) Wireless Bluetooth(R)
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.
某些英特尔（Intel）无线蓝牙（Bluetooth）驱动在 Ring 0（内核）中存在基于栈的缓冲区溢出漏洞，可能导致拒绝服务（DoS）。具备未认证用户身份的普通软件攻击者，在无需特殊内部知识且无需用户交互的情况下，通过相邻访问方式发起低复杂度攻击，即可触发该漏洞。该漏洞可能影响系统的可用性（高），但不会损害其保密性（无）和完整性（无）；由此引发的后续系统影响为：保密性（无）、完整性（无）、可用性（无）。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
Stack-based buffer overflow for some Intel(R) Wireless Bluetooth(R) within Ring 0: Kernel may allow a denial of service. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are 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.
