En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: lantiq: corrige la corrupción de la memoria en el anillo RX En una situación en la que falla la asignación de memoria o el mapeo dma, se programa una dirección no válida en el descriptor. Esto puede provocar daños en la memoria. Si la asignación de memoria falla, DMA debería reutilizar el skb y el mapeo anteriores y descartar el paquete. Este parche también incrementa el contador de caídas de rx.
