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

io_uring/rw: defer fsnotify calls to task context

We can't call these off the kiocb completion as that might be off soft/hard irq context. Defer the calls to when we process the task_work for this request. That avoids valid complaints like:

WID-SEC-W-2025-2920 — Linux Kernel: Mehrere Schwachstellen

2026-10-01T16:42:32.685022+00:00

Ein Angreifer kann mehrere Schwachstellen im Linux-Kernel ausnutzen, um nicht näher spezifizierte Angriffe durchzuführen, die möglicherweise zu einer Denial-of-Service- Bedingung führen oder eine Speicherbeschädigung verursachen können.
