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。

  - pariscled修复 start_task() 中的潜在 null-ptr-deref start_task() 调用 create_singlethread_workqueue() 且未检查 ret 值可能会返回 NULL。并且可能会发生 null-ptr-derefstart_task() create_singlethread_workqueue() # failed, led_wq is NULL queue_delayed_work() queue_delayed_work_on() __queue_delayed_work() # warn here, but continue __queue_work() # access wq->flags, null-ptr -deref 检查 ret 值如果为 NULL则返回 -ENOMEM。 (CVE-2022-50415)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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。

  - pariscled修正 start_task() start_task() 呼叫 create_singlethread_workqueue() 中潛在的 null-ptr-deref 且未檢查可能傳回 NULL 的 ret 值。並且可能發生 null-ptr-deref: start_task() create_singlethread_workqueue() # 失敗led_wq 為 NULL queue_delayed_work() queue_delayed_work_on() __queue_delayed_work() # 此處顯示警告但繼續 __queue_work() # 存取 wq->flags, null-ptr -deref 檢查 ret 值若其為 NULL則傳回 -ENOMEM。 (CVE-2022-50415)

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。

  - pariscledstart_task() における潜在的な null-ptr-deref を修正。start_task() は create_singlethread_workqueue() を呼び出し、NULL を返す可能性がある ret 値をチェックしませんでした。null-ptr-deref が発生する可能性があります start_task() create_singlethread_workqueue() # 失敗しました、led_wq は NULL キュー_delayed_work() queue_delayed_work_on() __queue_delayed_work() # ここで警告になりますが、__queue_work() を続行します # access wq->flags、null-ptr -deref ret 値をチェックし、NULL の場合は -ENOMEM を返します。CVE-2022-50415

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。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992382 advisory.

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

    parisc: led: Fix potential null-ptr-deref in start_task()

    start_task() calls create_singlethread_workqueue() and not checked the     ret value, which may return NULL. And a null-ptr-deref may happen:

    start_task()         create_singlethread_workqueue() # failed, led_wq is NULL         queue_delayed_work()             queue_delayed_work_on()
                __queue_delayed_work()  # warning here, but continue
                    __queue_work()      # access wq->flags, null-ptr-deref

    Check the ret value and return -ENOMEM if it is NULL.

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.
