Description OSIDB Bzimport 2026-07-19 15:03:11 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: airoha: Add missing bits in airoha_qdma_cleanup_tx_queue()

Similar to airoha_qdma_cleanup_rx_queue(), reset DMA TX descriptors in
airoha_qdma_cleanup_tx_queue routine. Moreover, reset TX_DMA_IDX to
TX_CPU_IDX to notify the NIC the QDMA TX ring is empty.
