This vulnerability involves improper input validation (CWE-20) in the modem IMS component of multiple Unisoc chipset models (SC7731E, SC9832E, SC9863A, T310, T610, T618, T7200, T7225, T7250, T7255, T7280, T7300, T8100, T9100, T8200, T8300) running Android 13 to 16. The flaw can be exploited remotely without privileges or user interaction to cause a denial of service condition, impacting system availability. The CVSS 3.1 base score is 7.5, reflecting high severity due to network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability. No patch or official remediation level has been published by Unisoc as of the vulnerability disclosure date.

The vulnerability allows a remote attacker to cause a denial of service on affected devices by exploiting improper input validation in the modem IMS component. This does not affect confidentiality or integrity but can disrupt device availability. No additional execution privileges or user interaction are required for exploitation. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level has been published by Unisoc, users and administrators should monitor vendor communications for updates. Until a patch is available, consider network-level protections to limit exposure to potentially malicious inputs targeting the modem IMS component.
