CVE-2026-17053

The SMBus driver API exposed smbussmbalertremovecb and smbushostnotifyremovecb as Zephyr syscalls. Their verifiers in drivers/smbus/smbushandlers.c validated only the dev argument with KSYSCALLOBJdev, KOBJDRIVERSMBUS and forwarded the caller-supplied struct smbuscallback cb pointer into kernel-mo...
