Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: fix DMA device NULL pointer dereference The DMA device pointer `dma_dev` was being dereferenced before ensuring that `cdns_ctrl->dmac` is properly initialized. Move the assignment of `dma_dev` after successfully acquiring the DMA channel to ensure the pointer is valid before use.
