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 CPU: 28 UID: 42 PID: 2255 Comm: wireplumber Tainted: G W L 6.12.0-10-133577cad6bf48e5a7848c4338124081393bfe8a+ #759 debug_dma_unmap_page+0xe9/0xf0 snd_dma_wc_free+0x85/0x130 [snd_pcm] snd_pcm_lib_free_pages+0x1e3/0x440 [snd_pcm] snd_pcm_common_ioctl+0x1c9a/0x2960 [snd_pcm] snd_pcm_ioctl+0x6a/0xc0 [snd_pcm] ...
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.
