      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: microchip-core: ensure TX and RX FIFOs are empty at start of a transfer\n\nWhile transmitting with rx_len == 0, the RX FIFO is not going to be\nemptied in the interrupt handler. A subsequent transfer could then\nread crap from the previous transfer out of the RX FIFO into the\nstart RX buffer. The core provides a register that will empty the RX and\nTX FIFOs, so do that before each transfer."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spi: microchip-core: asegúrese de que los FIFO de TX y RX estén vacíos al inicio de una transferencia. Mientras se transmite con rx_len == 0, el FIFO de RX no se vaciará en la interrupción entrenador de animales. Una transferencia posterior podría leer basura de la transferencia anterior desde el RX FIFO al búfer de inicio de RX. El núcleo proporciona un registro que vaciará los FIFO RX y TX, así que hágalo antes de cada transferencia."
