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

  - f2fs：修正 f2fs_balance_fs（gc_merge） 路徑中的潛在鎖死 當我們使用gc_merge掛載選項掛載裝置時，我們可能會遇到以下潛在鎖死： Kworker GC trehad 截斷器 - f2fs_write_cache_pages - f2fs_write_single_data_page - f2fs_do_write_data_page - folio_start_writeback --- 在對開本上設定回寫旗標 - f2fs_outplace_write_data： 內部 bio 快取中快取的對開本 - f2fs_balance_fs - wake_up（gc_thread）：喚醒 gc 執行緒以執行前台 GC - finish_wait（fggc_wq）：等待等候佇列
    ---等待 GC 執行緒完成工作 - truncate_inode_pages_range - __filemap_get_folio（， FGP_LOCK）
    ---鎖定對開本 - truncate_inode_partial_folio - folio_wait_writeback ---等待清除回寫 - do_garbage_collect - move_data_page - f2fs_get_lock_data_folio - 對開本上的鎖定 ---在對開本的鎖定上被封鎖 為了避免這種鎖死，讓我們呼叫以下函式GC_MERGE在 f2fs_balance_fs（） 路徑中提交快取的 bio，就像我們在NOGC_MERGE路徑中所做的那樣。- f2fs_submit_merged_write（sbi、DATA）;- f2fs_submit_all_merged_ipu_writes（SBI）;（CVE-2026-68459）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - f2fs:f2fs_balance_fs() のパスgc_merge潜在的なデッドロックを修正します。マウントオプションを指定gc_mergeしてデバイスをマウントする際、以下の潜在的なデッドロックが発生する可能性があります:Kworker GC trehad Truncator - f2fs_write_cache_pages - f2fs_write_single_data_page - f2fs_do_write_data_page - folio_start_writeback --- Folio に書き戻しフラグを設定します - f2fs_outplace_write_data: 内部 bio キャッシュのキャッシュされたフォリオ - f2fs_balance_fs - wake_up(gc_thread) :gc スレッドをウェイクアップしてフォアグラウンド GC を実行します - finish_wait(fggc_wq) :waitqueue で待機します

The remote Ubuntu 24.04 LTS / 26.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8726-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - f2fs: fix potential deadlock in gc_merge path of f2fs_balance_fs() When we mount device w/ gc_merge mount     option, we may suffer below potential deadlock: Kworker GC trehad Truncator - f2fs_write_cache_pages -     f2fs_write_single_data_page - f2fs_do_write_data_page - folio_start_writeback --- set writeback flag on     folio - f2fs_outplace_write_data : cached folio in internal bio cache - f2fs_balance_fs -     wake_up(gc_thread) : wake up gc thread to run foreground GC - finish_wait(fggc_wq) : wait on the waitqueue

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the linux package has been released.

The remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8727-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)
