Title: Linux Kernel 'drivers/acpi/acpica/nseval.c'本地信息泄露漏洞

Description:

Linux kernel是美国Linux基金会发布的操作系统Linux所使用的内核。

Linux kernel 4.12.9及之前的版本中的drivers/acpi/acpica/nseval.c文件的‘acpi_ns_evaluate()’函数存在本地信息泄露漏洞，该漏洞源于程序未能清除缓存的操作数。本地攻击者可借助特制的ACPI表单利用该漏洞获取内核内存中的敏感信息，并绕过KASLR保护机制。

Severity: 中

Summary

The acpi_ns_evaluate() function in drivers/acpi/acpica/nseval.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.
