CVE-2026-10674

The CVE describes a Denial of Service risk in the NXP LPUART driver for Zephyr (drivers/serial/uart_mcux_lpuart.c). When CONFIG_UART_USE_RUNTIME_CONFIGURE is enabled, LPUART_Deinit() is called at the start of mcux_lpuart_configure(), which disables peripheral clocks. Validation of the requested c...
