CVE-2026-74653

A flaw was found in the Linux kernel's 8250of serial driver, specifically affecting NXP LPC32xx UARTs. A local user could repeatedly open a specific serial port, triggering a stuck RX character-timeout interrupt. This leads to an interrupt storm that can livelock the CPU, resulting in a Denial of...
