smbus validation

The smbus validation tag covers discussions about SMBus block-read length validation flaws in Linux kernel drivers, such as the Samsung s3c24xx I2C host driver. These issues involve bounds-checking where the first byte of a received SMBus message could be used before confirming it is within legal range. While not typically remote-code-execution vulnerabilities, they are security-relevant because they reside in the kernel, handle hardware-facing input, and affect long-lived embedded Linux deployments. Content under this tag focuses on vulnerability triage, kernel patches, and risk assessment for niche hardware paths.
