CVE-2026-40694

Quick assessment

Affected
n/a Hyperscan
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 v5.4.2.1 之前的某些 Hyperscan 版本中,Ring 3(用户态)存在越界写入漏洞。该漏洞可能被利用导致拒绝服务(DoS)。具备已认证用户权限的非特权软件攻击者,结合低复杂度攻击手段,即可触发拒绝服务。该漏洞可通过本地访问利用,无需特殊内部知识,且不需要用户交互。此潜在漏洞可能对受影响系统的保密性(低)、完整性(低)和可用性(高)造成影响;一旦利用成功,后续将导致系统保密性(无)、完整性(无)和可用性(无)受损。

Vulnerability Description
Out-of-bounds write for some Hyperscan before version v5.4.2.1 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 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.
