Technical details

The modem firmware lacks proper sanitization of sensitive data before writing crash dumps to storage, allowing an authenticated local attacker to retrieve unfiltered information via CWE-20 (Improper Input Validation). The vulnerability requires local access and user-level privileges, exposing confidential data in the confidentiality domain. No remote exploitation path exists.
