CVE-2026-53299 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: airoha: Move ndesc initialization at end of airoha_qdma_init_tx() If queue entry list allocation fails in airoha_qdma_init_tx_queue routine, airoha_qdma_cleanup_tx_queue() will trigger a NULL pointer dereference accessing the queue entry array. The issue is due to the early ndesc initialization in airoha_qdma_init_tx_queue(). Fix the issue moving ndesc initialization at end of airoha_qdma_init_tx routine.
A NULL pointer dereference vulnerability has been identified in the Linux kernel's Airoha Ethernet driver. This issue arises in the 'airoha_qdma_init_tx_queue' function, where the initialization of the 'ndesc' variable occurs too early. If the allocation of the queue entry list fails, the 'airoha_qdma_cleanup_tx_queue' function will attempt to access the queue entry array, leading to a NULL pointer dereference. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed by moving the 'ndesc' initialization to the end of the 'airoha_qdma_init_tx' function. Users should upgrade to the latest version of the Linux kernel where this fix has been applied.
