Linux Distros 未修補的弱點：CVE-2023-53511
medium Nessus Plugin ID 269561
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
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。- io_uring修正 fs 不支援 nowait 緩衝讀取時發生的 fget 洩漏。使用 io_uring 在 ocfs2 上執行 link-cp 時Heming 報告一個錯誤。 [1] 執行下列步驟可能會重現此錯誤 mount -t ocfs2 /dev/vdc /mnt/ocfs2 cp testfile /mnt/ocfs2/ ./link-cp /mnt/ocfs2/testfile /mnt/ocfs2/testfile.1 umount /mnt/ocfs2 然後 umount 將會失敗而且它會輸出 umount: /mnt/ocfs2: target is busy。在追踪卸載時它會將 mnt_get_count() 歸咎於未如預期傳回。針對相關程式碼流程上的 fget()/fput() 進行深入調查我最終發現由於 ocfs2 不支援 nowait 緩衝讀取因此有 fget() 洩漏。
io_issue_sqe |-io_assign_file // 先執行 fget() |-io_read |-io_iter_do_read |-ocfs2_file_read_iter // 傳回 -EOPNOTSUPP |-kiocb_done |-io_rw_done |-__io_complete_rw_common // 設定 REQ_F_REISSUE |-io_resubmit_prep |-io_req_prep_async // 覆寫 req->檔案發生洩漏。這是由 v5.18 中的認可 a196c78b5443 引入。若已指派則不重新指派 req->file 以修正此問題。 [1] https://lore.kernel.org/ocfs2-devel/[email protected]/T/#t(CVE-2023-53511)
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
