HOTPATCH METHOD FOR VULNERABILITIES IN EMBEDDED IOT DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240053978 titled 'HOTPATCH METHOD FOR VULNERABILITIES IN EMBEDDED IOT DEVICES

Simplified Explanation

The present disclosure describes a hotpatch method for vulnerabilities in embedded Internet of Things (IoT) devices. The method involves acquiring vulnerability information of the devices, selecting a patching mode based on different vulnerability types, obtaining an eBPF patch bytecode file and configuration file from a server, compiling the eBPF patch bytecode to generate a patch binary code file and configuration information, and triggering the patch binary code to patch the vulnerabilities.

  • Acquiring vulnerability information of embedded IoT devices
  • Selecting a patching mode based on different vulnerability types
  • Obtaining eBPF patch bytecode file and configuration file from a server
  • Compiling eBPF patch bytecode to generate a patch binary code file and configuration information
  • Triggering the patch binary code to patch the vulnerabilities

Original Abstract Submitted

the present disclosure discloses a hotpatch method for vulnerabilities in embedded internet of things (iot) devices. the method includes acquiring vulnerability information of the embedded iot devices to be patched; selecting a corresponding vulnerability patching mode based on different vulnerability types of the vulnerability information, and acquiring an ebpf patch bytecode file (first patch) and an ebpf patch code configuration file from a server according to the vulnerability patching mode; compiling the ebpf patch bytecode based on the ebpf patch bytecode and the ebpf patch code configuration file to generate a patch binary code file (second patch) and configuration information of the patch binary code; and adopting three approaches to trigger the patch binary code to patch the vulnerability information based on the configuration information and the vulnerability patching mode.
