CVE-2026-63859

A flaw was found in the Linux kernel's airoha network driver. The airoha_qdma_cleanup_tx_queue() routine, responsible for cleaning up transmit queues, was missing critical steps. This omission could lead to improper resetting of Direct Memory Access (DMA) transmit descriptors and incorrect notification to the network interface controller (NIC) about the state of the transmit ring. Consequently, this could result in resource mismanagement within the network driver.
