CVE-2026-90585 Renesas RA SCI UART driver: unacknowledged receive-error interrupt causes a permanent interrupt storm and CPU lockup

The Renesas RA SCI UART driver's receive-error ISR, uartrascieriisr in drivers/serial/uartrenesasrasci.c, acknowledged the error condition only when a Zephyr interrupt-driven callback had already been registered. With CONFIGUARTINTERRUPTDRIVEN=y and CONFIGUARTASYNCAPI=n, if data-usercb is NULL th...
