n the Linux kernel, the following vulnerability has been resolved: xhci: Fix null pointer dereference when host dies Make sure xhci_free_dev() and xhci_kill_endpoint_urbs() do not race and cause null pointer dereference when host suddenly dies. Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id] virt device at the same time that xhci_kill_endpoint_urbs() tries to loop through all the device's endpoints, checking if there are any cancelled urbs left to give back. hold the xhci spinlock while freeing the virt device

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: xhci: corrige la desreferencia del puntero nulo cuando el host muere. Asegúrese de que xhci_free_dev() y xhci_kill_endpoint_urbs() no corran y provoquen una desreferencia del puntero nulo cuando el host muere repentinamente. El núcleo USB puede llamar a xhci_free_dev(), lo que libera el dispositivo virt xhci->devs[slot_id] al mismo tiempo que xhci_kill_endpoint_urbs() intenta recorrer todos los endpoints del dispositivo, verificando si quedan urbs canceladas para devolver. mantenga presionado el xhci spinlock mientras libera el dispositivo virt
