Vulnerability from fkie_nvd - Published: 2026-07-01 14:16 - Updated: 2026-07-23 21:33

Severity

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

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 "memory-region" 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->base; // line 1156 num_desc = div_u64(rmem->size, 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.

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-\u003ebase;                          // line 1156\n    num_desc = div_u64(rmem-\u003esize, 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."
