"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: stm32: dcmi: fix some error handling bugs in probe()\n\nThere are a few issues here:\n\n1) After we assign:\n chan = dma_request_chan(&pdev->dev, \"tx\");\n Then the error paths need to clean up before returning. The first\n error path does a direct return.\n2) The error paths check \"dcmi->mdma_chan\" but that is not assigned\n until later so it results in memory leaks. Test \"mdma_chan\"\n instead.\n3) The error handling calls dma_release_channel(dcmi->dma_chan) before\n \"dcmi->dma_chan\" has been assigned which leads to a NULL pointer\n dereference. Use the \"chan\" variable instead.\n\nI also moved the call to dma_release_channel() after the call to\ndma_release_channel() so it mirrors the allocation code better."
