Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: microchip-core: ensure TX and RX FIFOs are empty at start of a transfer<br /> <br /> While transmitting with rx_len == 0, the RX FIFO is not going to be<br /> emptied in the interrupt handler. A subsequent transfer could then<br /> read crap from the previous transfer out of the RX FIFO into the<br /> start RX buffer. The core provides a register that will empty the RX and<br /> TX FIFOs, so do that before each transfer.
