CVE-2026-63859
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.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
