A dangerous vulnerability in Realtek chipsets used in hundreds of thousands of smart devices from at least 65 vendors is currently under attack from a notorious DDoS botnet gang.

The attacks started last week, according to a report from IoT security firm SAM, and began just three days after fellow security firm IoT Inspector published details about the vulnerability on its blog.

Tracked as CVE-2021–35395, the vulnerability is part of four issues IoT Inspector researchers found in the software development kit (SDK) that ships with multiple Realtek chipsets (SoCs).
