CVE-2026-74654

A flaw was found in the Linux kernel's 8250dma serial driver. When a serial port is closed while an RX receive transfer is active, a stale state can persist where the rxrunning flag remains set even though the receive channel is no longer available. If the port is subsequently reopened, a specifi...

CVE-2026-74652

A flaw was found in the Linux kernel's amba-pl011 serial driver. The RS485 trigger high-resolution timers hrtimers can fire after the device management devm-managed port is freed. This occurs because the timers are not properly canceled before the interrupt request IRQ is freed, allowing a...
