Summary
In the Linux kernel, the following vulnerability has been resolved: io_uring: check if we need to reschedule during overflow flush In terms of normal application usage, this list will always be empty. And if an application does overflow a bit, it'll have a few entries. However, nothing obviously prevents syzbot from running a test case that generates a ton of overflow entries, and then flushing them can take quite a while. Check for needing to reschedule while flushing, and drop our locks and do so if necessary. There's no state to maintain here as overflows always prune from head-of-list, hence it's fine to drop and reacquire the locks at the end of the loop.

Y si una aplicación se desborda un poco, tendrá algunas entradas. Sin embargo, obviamente nada impide que syzbot ejecute un caso de prueba que genere un montón de entradas de desbordamiento, y luego vaciarlas puede llevar bastante tiempo. Verifique la necesidad de reprogramar durante el vaciado y elimine nuestros bloqueos y hágalo si es necesario. No hay ningún estado que mantener aquí, ya que los desbordamientos siempre se podan desde el principio de la lista, por lo tanto, está bien eliminar y volver a adquirir los bloqueos al final del bucle.",
