Affected
n/a kernel
Exploitation
Confirmed exploitation in the wild; remediate immediately
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel 存在安全漏洞，该漏洞源于新管道缓冲区结构的“flag”变量在 Linux 内核中的 copy_page_to_iter_pipe 和 push_pipe 函数中缺乏正确初始化。非特权本地用户利用该漏洞可以提升权限至root。以下产品和版本受到影响：Linux Kernel 5.8-5.16.11、5.8-5.15.25、5.8-5.10.102。

Vulnerability Description
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
