In the Linux kernel, the following vulnerability has been resolved: spi: ti-qspi: fix use-after-free after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to clear the DMA channel pointer also if buffer allocation fails to avoid passing a pointer to the released channel to the DMA engine (or trying to free the channel a second time on late probe errors or driver unbind). This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.
