Doc Text:
A vulnerability was found in the Linux kernel's handling of winch IRQs. This issue involves the registration of winch IRQs before adding winch handlers to the winch_handlers list. This oversight could potentially lead to improper IRQ handling and impact system stability or security. This issue has been resolved by ensuring that winch handlers are added to the list before the IRQs are registered.
