CVE-2026-43061

CVE-2026-43061 (Linux kernel): The serial8250 TX DMA deadlock was fixed. The root cause was that dmaengine_terminate_async did not guarantee the __dma_tx_complete callback would run, and that callback is the only place where dma->tx_running is cleared. If a TX DMA transaction is canceled and t...
