      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: airoha: Add NULL check for of_reserved_mem_lookup() in airoha_qdma_init_hfwd_queues()\n\nof_reserved_mem_lookup() may return NULL if the reserved memory region\nreferenced by the \"memory-region\" phandle is not found in the reserved\nmemory table (e.g. due to a misconfigured DTS or a removed\nmemory-region node).  The current code dereferences the returned\npointer without checking for NULL, leading to a kernel NULL pointer\ndereference at the following lines:\n\n    dma_addr = rmem->base;                          // line 1156\n    num_desc = div_u64(rmem->size, buf_size);       // line 1160\n\nAdd a NULL check after of_reserved_mem_lookup() and return -ENODEV if\nthe lookup fails, which is consistent with the existing error handling\nfor of_parse_phandle() failure in the same code block.",
