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...

ROS-20260825-73-0010

The vulnerability of the s3c24xxserialgetclk function in the drivers/tty/serial/samsungtty.c module of the console TTY driver in the Linux kernel’s serial port is related to the failure to release resources after their useful life has expired. Exploiting this vulnerability could allow an attacker...

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...
