    Added Description In the Linux kernel, the following vulnerability has been resolved:

    ALSA: memalloc: prefer dma_mapping_error() over explicit address checking

    With CONFIG_DMA_API_DEBUG enabled, the following warning is observed:

    DMA-API: snd_hda_intel 0000:03:00.1: device driver failed to check map error[device address=0x00000000ffff0000] [size=20480 bytes] [mapped as single]
    WARNING: CPU: 28 PID: 2255 at kernel/dma/debug.c:1036 check_unmap+0x1408/0x2430

    Check for returned DMA addresses using specialized dma_mapping_error()
    helper which is generally recommended for this purpose by
    Documentation/core-api/dma-api.rst.
