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。

  - 已解決 Linux 核心中的下列弱點：workqueue: Put the pwq after detaching the rescuer from the pool The commit 68f83057b913(workqueue: Reap workers via kthread_stop() and remove detach_completion) adds code to reap the normal workers but mistakenly does not handle the rescuer and also removes the code waiting for the rescuer in put_unbound_pool(), which caused a use-after-free bug reported by Cheung Wall. To avoid the use-after-free bug, the pool's reference must be held until the detachment is complete. Therefore, move the code that puts the pwq after detaching the rescuer from the pool. (CVE-2025-21786)
