Realtek

Realtek's vulnerability footprint spans a well-represented portfolio of embedded networking and wireless components, including wireless drivers, Wi-Fi adapters, and firmware platforms such as the RTL819x Jungle SDK and RTL8195a series, that are widely integrated into consumer routers, IoT devices, and network appliances. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated tendency toward critical severity, and a moderate share acquire public exploit code. The exposure recurs through memory-safety weakness classes dominated by buffer overflows—including stack-based, heap-based, and out-of-bounds writes—reflecting the low-level nature of firmware and driver codebases and their limited opportunity for modern defensive tooling. Defenders should prioritize inventory and patching of internet-exposed network devices shipping Realtek components, as these embedded platforms often remain in service well beyond vendor support timelines; current exploitation and severity counts are shown alongside this summary.
