Executive Summary

CVE-2025-71251 is a high-severity vulnerability found in the Modem IMS component of certain chipsets such as SC7731E, SC9832E, and SC9863A. The issue arises from improper input validation, which means the system does not correctly check or sanitize incoming data. This flaw allows a remote attacker to cause a system crash, resulting in a denial of service (DoS) without needing any additional execution privileges.

• The vulnerability affects multiple Android versions, from Android 13 to Android 16.
• It is classified under CWE-20 (Improper Input Validation).
• The attack vector is network-based, meaning it can be exploited remotely.
