CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of DMA transfers in the mtd subsystem, specifically within the lpc32xx_slc driver. A failure to properly manage timeout conditions can lead to a situation where a timed-out DMA transfer is incorrectly reported as successful, potentially allowing unauthorized access to memory buffers. Organizations using affected Linux systems, particularly those relying on NAND flash memory operations, should prioritize patching to mitigate potential data integrity and security risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: lpc32xx_slc: fail DMA transfer on completion timeout lpc32xx_xmit_dma() waits for the DMA completion callback but ignores wait_for_completion_timeout(). A timed out DMA transfer is therefore unmapped and reported as successful to the NAND read/write path. Return -ETIMEDOUT when the completion wait expires. Terminate the DMA channel before unmapping the scatterlist so the timed out transfer cannot continue to access the buffer after the error is returned.
