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。

  - 在 Linux 内核中，已解决以下漏洞： cachestat: fix page cache statistics permission checking When the 'cachestat()' system call was added in commit cf264e1329fb (cachestat:
    implement cachestat syscall), it was meant to be a much more convenient (and performant) version of mincore() that didn't need mapping things into the user virtual address space in order to work. But it ended up missing the check for writability or ownership fix for mincore(), done in commit 134fca9063ad (mm/mincore.c: make mincore() more conservative). This just adds equivalent logic to 'cachestat()', modified for the file context (rather than vma). (CVE-2025-21691)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
