About this tag
The i2c security tag on WindowsForum.com covers discussions about vulnerabilities and security issues related to the I2C (Inter-Integrated Circuit) bus, particularly in Linux environments. Recent content highlights CVE-2026-64191, a Linux kernel vulnerability in the I2C stub driver that can lead to out-of-bounds memory access. The risk is limited to development and test systems where the driver is explicitly loaded, but it is relevant for Linux developers, hardware validation teams, and Windows users running custom Linux kernels, such as in WSL 2. The tag provides insights into I2C security risks, kernel patches, and best practices for securing I2C implementations.
