CVE-2022-40262— The arbitrary write vulnerability in S3Resume2Pei leads to arbitrary code execution during PEI phase.

The arbitrary write vulnerability in S3Resume2Pei leads to arbitrary code execution during PEI phase.

A potential attacker can execute an arbitrary code at the time of the PEI phase and influence the subsequent boot stages. This can lead to the mitigations bypassing, physical memory contents disclosure, discovery of any secrets from any Virtual Machines (VMs) and bypassing memory isolation and confidential computing boundaries. Additionally, an attacker can build a payload which can be injected into the SMRAM memory. This issue affects: Module name: S3Resume2Pei SHA256: 7bb29f05534a8a1e010443213451425098faebd45948a4642db969b19d0253fc Module GUID: 89E549B0-7CFE-449D-9BA3-10D8B2312D71

Intel NUC M15 缓冲区错误漏洞

Intel NUC M15是美国英特尔（Intel）公司的一种笔记本电脑套件。 Intel NUC M15 Laptop Kit BC0076之前版本存在安全漏洞，该漏洞源于潜在的攻击者可以在PEI阶段执行任意代码并影响后续启动阶段。 这可能导致绕过缓解措施、物理内存内容泄露、从任何虚拟机中发现任何秘密以及绕过内存隔离和机密计算边界，攻击者可以构建可以注入SMRAM内存的有效载荷。
