CVE-2026-98204

A flaw was found in the Linux kernel's Synaptics RMI4 SMBus driver. When chunking write requests across the System Management Bus SMBus, the driver miscalculates the remaining data length for the final block. A local user can exploit this issue to trigger an out-of-bounds read past the input...

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...
