In the Linux kernel, the following vulnerability has been resolved: dmaengine: imx-sdma: Fix a possible memory leak in sdmatransferinit If the function sdmaloadcontext() fails, the sdmadesc will be freed, but the allocated desc->bd is forgot to be freed. We already met the sdmaload_context() failure case and the log as below: [ 450.699064] imx-sdma 30bd0000.dma-controller: Timeout waiting for CH0 ready ... In this case, the desc->bd will not be freed without this change.
