Unauthenticated information disclosure via mishandled modem error
Published Apr 8, 2024 · Updated Mar 13, 2025
Information disclosure in UNISOC modem-ps-nas-ngmm on Android 12 through 14 allows remote attackers to expose data via network traffic. The component enters undefined behavior because its error path handles an exceptional condition incorrectly; UNISOC has not disclosed the triggering input or exposed data. No privileges or user interaction are required, but the published impact description conflicts with the accompanying impact metrics, leaving the precise consequence unresolved.
