Vulnerability Response Process

During the vulnerability handling process, PSIRT will limit information only to employees relevant to vulnerability response. Meanwhile, PSIRT will also request the reporter of the vulnerability to refrain from sharing vulnerability information with others.

HiSilicon (Shanghai) provides security vulnerability information on its official website through:
Security Notice (SN):
rapidly responds to suspected vulnerabilities in HiSilicon (Shanghai) products that will or have been disclosed to the public or security issues.
Security Advisory (SA):
informs customers of a specific vulnerability, including its severity, potential impact on services, and remediation solutions. It provides feasible vulnerability remediation solutions to computer security incident response teams (CSIRTs) of customers or equivalent organizations to support customers as they make risk-related decisions on live networks.

We have established a comprehensive vulnerability handling process based on the ISO 29147/30111 standard. This process is as follows:

Vulnerability Response Process
