The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986963 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    ubifs: Fix races between xattr_{set|get} and listxattr operations

    UBIFS may occur some problems with concurrent xattr_{set|get} and     listxattr operations, such as assertion failure, memory corruption,     stale xattr value[1].

    Fix it by importing a new rw-lock in @ubifs_inode to serilize write     operations on xattr, concurrent read operations are still effective,     just like ext4.

    [1] https://lore.kernel.org/linux-mtd/20200630130438.141649-1-houtao1@huawei.com

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

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

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。

  - ubifsxattr_{set|get} と listxattr 操作の間の競合を修正します。UBIFS では、xattr_{set|get} と listxattr 操作を同時に行うことで、アサーション失敗、メモリ破損、古い xattr 値[1] などの問題が発生する可能性があります。@ubifs_inode の新しい rw-lock をインポートして xattr の書き込み操作をシリアル化することでこれを修正します。ext4 と同様に、同時読み取り操作は依然として有効です。 [1] https://lore.kernel.org/linux-mtd/20200630130438.141649-1-houtao1@huawei.comCVE-2021-47351]

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

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。

  - ubifs修正 xattr_{set|get} 和 listxattr 作業間的爭用情形 UBIFS 可能會在同時進行 xattr_{set|get} 和 listxattr 作業時發生的一些問題例如宣告失敗、記憶體損毀、過時 xattr 值 [1]。修正方法是在 @ubifs_inode 中匯入新的 rw-lock以序列化 xattr 上的寫入作業並行讀取作業仍然有效如同 ext4。 [1] https://lore.kernel.org/linux-mtd/20200630130438.141649-1-houtao1@huawei.com (CVE-2021-47351)

請注意，Nessus 依賴供應商報告的套件存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - ubifs修复 xattr_{set|get} 和 listxattr 操作之间的争用 UBIFS 可能会发生并发 xattr_{set|get} 和 listxattr 操作的某些问题例如断言失败、内存损坏、过时的 xattr 值[1]。通过在 @ubifs_inode 中导入新的 rw-lock修复此问题以使 xattr 上的写入操作序列化并发读取操作仍然有效就像 ext4 一样。 [1] https://lore.kernel.org/linux-mtd/20200630130438.141649-1-houtao1@huawei.com (CVE-2021-47351)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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

  - ubifs: Fix races between xattr_{set|get} and listxattr operations UBIFS may occur some problems with     concurrent xattr_{set|get} and listxattr operations, such as assertion failure, memory corruption, stale     xattr value[1]. Fix it by importing a new rw-lock in @ubifs_inode to serilize write operations on xattr,     concurrent read operations are still effective, just like ext4.

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