In the Linux kernel, the following vulnerability has been resolved: virtio_pmem: Check device status before requesting flush If a pmem device is in a bad status, the driver side could wait for host ack forever in virtio_pmem_flush(), causing the system to hang. So add a status check in the beginning of virtio_pmem_flush() to return early if the device is not activated.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: virtio_pmem: comprobar el estado del dispositivo antes de solicitar la descarga. Si un dispositivo pmem está en mal estado, el lado del controlador podría esperar el commit del host para siempre en virtio_pmem_flush(), lo que provocaría que el sistema se cuelgue. Por lo tanto, agregue una comprobación de estado al comienzo de virtio_pmem_flush() para que vuelva antes si el dispositivo no está activado.
