What to do
AI-suggested
- Monitor Unisoc and device vendors for official patches addressing CVE-2025-61607 and apply them promptly upon release.
- Until patches are available, implement network-level filtering to detect and block malformed or suspicious NR modem packets that could trigger the vulnerability.
- Employ mobile device management (MDM) solutions to enforce security policies and quickly deploy updates to affected devices.
- Conduct regular network traffic analysis to identify anomalous patterns indicative of exploitation attempts targeting the modem.
- Limit exposure by restricting network access to critical devices, especially in sensitive environments, using VPNs or private APNs.
- Educate users and IT staff about the symptoms of modem crashes and establish incident response procedures to quickly address service disruptions.
- Collaborate with telecom providers to understand the deployment of Unisoc chipsets in their infrastructure and coordinate mitigation efforts.
- Review and update business continuity plans to account for potential mobile service outages caused by this vulnerability.
