In the Linux kernel, the following vulnerability has been resolved:spi: don't unoptimize message in spi_async()Calling spi_maybe_unoptimize_message() in spi_async() is wrong becausethe message is likely to be in the queue and not transferred yet. Thiscan corrupt the message while it is being used by the controller driver.spi_maybe_unoptimize_message() is already called in the correct placein spi_finalize_current_message() to balance the call tospi_maybe_optimize_message() in spi_async().
No PoCs from references.
