  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: at_xdmac: avoid null_prt_deref in at_xdmac_prep_dma_memset\n\nThe at_xdmac_memset_create_desc may return NULL, which will lead to a\nnull pointer dereference. For example, the len input is error, or the\natchan->free_descs_list is empty and memory is exhausted. Therefore, add\ncheck to avoid this.",
