Linux Distros 未修补的漏洞：CVE-2022-50239

high Nessus 插件 ID 264943

语言：

简介

Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。

描述

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

- cpufreqqcom修复只读内存区域中的写入此提交修复了因某些只读内存中的写入而造成的内核 oops[ 9.068287] 无法处理对虚拟地址 ffff800009240ad8 处的只读内存的内核写入。 snip.. [ 9.138790] 内部错误Oops: 9600004f [#1] PREEMPT SMP ..snip..

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
