CVE-2026-74653

CVE-2026-74653 affects the Linux kernel 8250_of serial driver on NXP LPC32xx (PORT_LPC3220) hardware. The UART can latch an RX character-timeout interrupt while the RX FIFO is empty; because the interrupt is level-triggered and re-fires immediately, it causes an interrupt storm that livelocks the...
