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。

  - 已解決 Linux 核心中的下列弱點：netfs: Fix the (non-)cancellation of copy when cache is temporarily disabled When the caching for a cookie is temporarily disabled (e.g. due to a DIO write on that file), future copying to the cache for that file is disabled until all fds open on that file are closed. However, if netfslib is using the deprecated PG_private_2 method (such as is currently used by ceph), and decides it wants to copy to the cache, netfs_advance_write() will just bail at the first check seeing that the cache stream is unavailable, and indicate that it dealt with all the content. This means that we have no subrequests to provide notifications to drive the state machine or even to pin the request and the request just gets discarded, leaving the folios with PG_private_2 set. Fix this by jumping directly to cancel the request if the cache is not available. That way, we don't remove mark3 from the folio_queue list and netfs_pgpriv2_cancel() will clean up the folios. This was found by running the generic/013 xfstest against ceph with an active cache and the -o fsc option passed to ceph.
    That would usually hang (CVE-2024-57941)

請注意，Nessus 依賴供應商報告的套件存在。
