CVE-2022-50024

CVE-2022-50024 affects the Linux kernel DMA engine (dmaengine) dw-axi-dmac. The issue occurs when axi_chan_dump_lli() is given a NULL LLI pointer, which can trigger an OOPS by attempting to read fields from a NULL structure. The fix is to print a NULL LLI and exit instead of dereferencing it. Aff...
