  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: rawnand: lpc32xx_slc: fail DMA transfer on completion timeout\n\nlpc32xx_xmit_dma() waits for the DMA completion callback but ignores\nwait_for_completion_timeout(). A timed out DMA transfer is therefore\nunmapped and reported as successful to the NAND read/write path.\n\nReturn -ETIMEDOUT when the completion wait expires. Terminate the DMA\nchannel before unmapping the scatterlist so the timed out transfer cannot\ncontinue to access the buffer after the error is returned.",
