i2c tunnel

About this tag
The i2c tunnel tag covers discussions about the Linux kernel's i2c-cros-ec-tunnel driver, which implements an I²C tunnel through a Chrome OS Embedded Controller (EC). A recent thread highlights CVE-2025-37781, a vulnerability in this driver that can cause a kernel NULL-pointer dereference and system crash when the EC parent device is not yet available. The upstream fix defers the driver probe to prevent the issue. This tag is relevant for users and developers working with Chrome OS devices, embedded controllers, and Linux kernel stability, particularly those interested in security patches and driver behavior.
