Description
In the Linux kernel, the following vulnerability has been resolved: media: stm32: dcmi: fix some error handling bugs in probe() There are a few issues here: 1) After we assign: chan = dma_request_chan(&pdev->dev, "tx"); Then the error paths need to clean up before returning. The first error path does a direct return. 2) The error paths check "dcmi->mdma_chan" but that is not assigned until later so it results in memory leaks. Test "mdma_chan" instead. 3) The error handling calls dma_release_channel(dcmi->dma_chan) before "dcmi->dma_chan" has been assigned which leads to a NULL pointer dereference. Use the "chan" variable instead. I also moved the call to dma_release_channel() after the call to dma_release_channel() so it mirrors the allocation code better.
