CVE-2026-57891
Quick assessment
Affected
n/a Intel(R) Server Board D50DNP and Intel(R) Server Board M50FCP
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 Ring 0 环境下的 UEFI 中，Intel® 服务器主板 D50DNP 和 M50FCP 的 XmlCliCommonDxe 组件存在越界写入漏洞。该漏洞可能允许攻击者提升权限。拥有特权的系统软件攻击者，结合高复杂度攻击手段，可在本地执行代码。在满足攻击条件且无需特殊内部知识的情况下，攻击者可通过本地访问触发该漏洞，且无需用户交互。此潜在漏洞可能对受影响系统的机密性（高）、完整性（高）和可用性（高）造成严重影响，进而引发后续的系统机密性（高）、完整性（高）和可用性（高）风险。

Vulnerability Description
Out-of-bounds write in the XmlCliCommonDxe for the Intel(R) Server Board D50DNP and Intel(R) Server Board M50FCP within Ring 0 UEFI may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable local code execution. 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 (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.
