CVE-2026-10674 DoS (hard fault) in NXP LPUART driver: unsupported runtime UART config leaves clocks disabled
The NXP LPUART serial driver drivers/serial/uartmcuxlpuart.c, when CONFIGUARTUSERUNTIMECONFIGURE is enabled, called LPUARTDeinit at the start of mcuxlpuartconfigure, which disables the LPUART peripheral clocks. The requested configuration is validated only afterwards in mcuxlpuartconfigurebasic,...
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...
