Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 Linux 核心中，已解決下列弱點： 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)

請注意，Nessus 依賴供應商報告的套件存在。
