Descriptions
In the Linux kernel, the following vulnerability has been resolved:
um: Add winch to winch_handlers before registering winch IRQ
Registering a winch IRQ is racy, an interrupt may occur before the winch is
added to the winch_handlers list.
If that happens, register_winch_irq() adds to that list a winch that is
scheduled to be (or has already been) freed, causing a panic later in
winch_cleanup().
Avoid the race by adding the winch to the winch_handlers list before
registering the IRQ, and rolling back if um_request_irq() fails.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: um: Agregar cabrestante a winch_handlers antes de registrar la IRQ del cabrestante Registrar una IRQ del cabrestante es picante, puede ocurrir una interrupción antes de que el cabrestante se agregue a la lista de winch_handlers. Si eso sucede, Register_winch_irq() agrega a esa lista un cabrestante que está programado para ser liberado (o que ya ha sido) liberado, causando pánico más adelante en winch_cleanup(). Evite la ejecución agregando el cabrestante a la lista winch_handlers antes de registrar la IRQ y retrocediendo si um_request_irq() falla.
