  "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(\u0026pdev-\u003Edev, \u0022tx\u0022);    Then the error paths need to clean up before returning.  The first    error path does a direct return. 2) The error paths check \u0022dcmi-\u003Emdma_chan\u0022 but that is not assigned    until later so it results in memory leaks.  Test \u0022mdma_chan\u0022    instead. 3) The error handling calls dma_release_channel(dcmi-\u003Edma_chan) before    \u0022dcmi-\u003Edma_chan\u0022 has been assigned which leads to a NULL pointer    dereference.  Use the \u0022chan\u0022 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.",
