Realtek SDK contains an improper input validation vulnerability in the miniigd SOAP service that allows remote attackers to execute malicious code via a crafted NewInternalClient request.
RealTek Jungle SDK contains multiple memory corruption vulnerabilities which can allow an attacker to perform remote code execution.
Realtek AP-Router SDK HTTP web server boa contains a buffer overflow vulnerability due to unsafe copies of some overly long parameters submitted in the form that lead to denial-of-service (DoS).
The rtl8192cd Wi-Fi kernel driver in the Realtek rtl819x Jungle SDK (all known versions through v3.4.14B) does not perform any access control checks on the writemem (ioctl 0x89F5) and readmem (ioctl 0x89F6) debug handlers, which are compiled into production builds via the unconditionally defined IOCTLDEBUGCMD macro in 8192cdcfg.h
