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.
