Remote DoS in Unisoc dpc modem via null pointer dereference

IdentifiersCVE-2025-3012CWE-476

CVE-2025-3012 is a vulnerability in the Unisoc dpc modem component caused by a null pointer dereference. According to the provided description, the flaw can trigger a system crash in the modem path, resulting in a remotely reachable denial-of-service condition. No additional execution privileges are required for exploitation. Based on the available information, the issue is limited to availability impact and there is no specific evidence here of code execution or privilege escalation.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can crash the affected system or modem-related subsystem, causing a denial of service. The provided information characterizes the issue as remotely triggerable and requiring no additional execution privileges, which means an attacker may be able to disrupt device availability over a network-reachable path exposed by the modem stack.

Mitigation

If you can’t patch tonight, do this now.

If a patch is not yet available, reduce exposure of the affected modem attack surface where operationally possible, including limiting untrusted remote interaction with modem-reachable services and prioritizing vendor firmware rollout for exposed devices. Because this is a modem-side remotely triggerable crash issue, practical mitigation is limited without the vendor fix; the primary mitigation is expedited patching and restricting use of affected devices in high-risk environments until updated.

Remediation

Patch, then assume compromise.

Apply the vendor/OEM security update that includes the fix for CVE-2025-3012. In the provided context, this issue is listed among Unisoc modem vulnerabilities addressed through the Android December 2025 security update ecosystem, so remediation depends on installing the relevant device firmware or vendor-integrated patch level supplied by the OEM/SoC vendor.
