UNISOC Modem Improper Input Validation Vulnerability Leading to Remote Denial-of-Service

A denial-of-service vulnerability has been identified in the UNISOC modem's IMS component, present in chipsets SC7731E, SC9832E, SC9863A, T310, T610, T618, T7200, T7225, T7250, T7255, T7280, T7300, T8100, T9100, T8200, and T8300. This vulnerability arises from improper input validation, which can cause a system crash, allowing for remote denial-of-service attacks without requiring additional execution privileges. The issue affects several versions of the software across different chipsets.

Impact

Exploitation of this vulnerability can lead to a remote denial-of-service condition, causing a system crash without any additional execution privileges required.
