  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: airoha: Add NULL check for of_reserved_mem_lookup() in airoha_qdma_init_hfwd_queues()  of_reserved_mem_lookup() may return NULL if the reserved memory region referenced by the \u0022memory-region\u0022 phandle is not found in the reserved memory table (e.g. due to a misconfigured DTS or a removed memory-region node).  The current code dereferences the returned pointer without checking for NULL, leading to a kernel NULL pointer dereference at the following lines:      dma_addr = rmem-\u003Ebase;                          // line 1156     num_desc = div_u64(rmem-\u003Esize, buf_size);       // line 1160  Add a NULL check after of_reserved_mem_lookup() and return -ENODEV if the lookup fails, which is consistent with the existing error handling for of_parse_phandle() failure in the same code block.",
