Linux Distros 未修補的弱點：CVE-2025-68821
medium Nessus Plugin ID 283648
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。- fuse修正 readahead 回收鎖死提交 e26ee4efbc79 (fuse只有在需要釋出時才配置 ff->release_args)如果伺服器未實作 open則略過配置 ff->release_args。不過在執行此動作時fuse_prepare_release() 現在會略過 inode 上的擷取參照這會讓系統在存在 inflight readahead 要求時從 dcache 中收回 inode。如果伺服器在處理 readahead 要求時觸發回收這會造成鎖死並回收嘗試收回正在讀取的檔案的 inode。由於作品集在 readahead 期間遭到鎖定因此當 reclaim 收回熔斷器 inode且 fuse_evict_inode() 嘗試從頁面快取中移除所有與 inode (truncate_inode_pages_range()) 的作品集時reclaim 將永遠封鎖等待鎖定因為 readahead 無法放棄因為其本身在回收中遭到封鎖所以鎖定c:336:10) fuse_evict_inode (fs/fuse/inode.c:161:2) 收回 (fs/inode.c:704:3) dentry_unlink_inode (fs/dcache.c:412:3) __dentry_kill (fs/dcache. c:615:3) shrink_kill (fs/dcache.c:1060:12) shrink_dentry_list (fs/dcache.c:1087:3) prune_dcache_sb (fs/dcache.c:1168:2) super_cache_scan (fs/super.c: 221:10) do_shrink_slab (mm/shrinker.c:435:9) shrink_slab (mm/shrinker.c:626:10) shrink_node (mm/vmscan.c:5951:2) shrink_zones (mm/vmscan.c:6195: 3) do_try_to_free_pages (mm/vmscan.c:6257:3) do_swap_page (mm/memory. c:4136:11) handle_pte_fault (mm/memory.c:5562:10) handle_mm_fault (mm/memory.c:5870:9) do_user_addr_fault (arch/x86/mm/fault.c:1338:10) handle_page_fault (arch/ x86/mm/fault.c:1481:3) exc_page_fault (arch/x86/mm/fault.c:1539:2) asm_exc_page_fault+0x22/0x27 透過在執行即使伺服器未實作 open 仍準備要發布的檔案。放置 fuse 檔案上的最後一個參照時會放置 inode 參照 (請參閱 fuse_file_put() -> fuse_release_end())。 (CVE-2025-68821)
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
