CVE-2026-53298 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: airoha: Move ndesc initialization at end of airoha_qdma_init_rx_queue() If queue entry or DMA descriptor list allocation fails in airoha_qdma_init_rx_queue routine, airoha_qdma_cleanup() will trigger a NULL pointer dereference running netif_napi_del() for RX queue NAPIs since netif_napi_add() has never been executed to this particular RX NAPI. The issue is due to the early ndesc initialization in airoha_qdma_init_rx_queue() since airoha_qdma_cleanup() relies on ndesc value to check if the queue is properly initialized. Fix the issue moving ndesc initialization at end of airoha_qdma_init_tx routine. Move page_pool allocation after descriptor list allocation in order to avoid memory leaks if desc allocation fails.
A NULL pointer dereference vulnerability has been identified in the Linux kernel's Airoha Ethernet driver. This issue arises in the 'airoha_qdma_init_rx_queue' function, where the initialization of the 'ndesc' variable occurs too early. If the allocation of the queue entry or DMA descriptor list fails, the 'airoha_qdma_cleanup' function will attempt to delete a NAPI (Network Active Polling Interface) that was never properly initialized, leading to a crash. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the latest kernel version can be found on the official Linux kernel website.
