CVE-2026-90590

The NXP ENET QoS Ethernet driver in drivers/ethernet/ethnxpenetqos serialises transmission with a binary semaphore, data-tx.txsem, taken in ethnxpenetqostx and returned only by the transmit-completion interrupt handler txdmadone. A frame that has been handed to the transmit DMA when the Ethernet...

CVE-2026-90590

The NXP ENET QoS Ethernet driver (drivers/ethernet/eth_nxp_enet_qos) in the Zephyr OS is vulnerable to a permanent denial of service (DoS) during link-down/link-up transitions. The root cause is that when a frame is handed to the transmit DMA and the link goes down, the completion interrupt never...
