CVE-2026-20753
Quick assessment
Affected
n/a Slim Bootloader may allow an escalation of privilege. System software adversary with a privileged user combined with a low 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.
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.
Intel Slim Bootloader是美国英特尔（Intel）公司的一个专为Intel平台设计的轻量级安全启动解决方案。 Intel Slim Bootloader存在输入验证错误漏洞，该漏洞源于UEFI固件中的整数溢出问题，可能导致权限提升，攻击者通过本地访问利用特权用户和低复杂度攻击实现本地代码执行。以下版本受到影响：Slim Bootloader。
