Information disclosure via missing LTE permission check
Published Sep 4, 2023 · Updated Sep 30, 2024
Information disclosure in the UNISOC LTE protocol stack on T760, T770, T820, and S8000 allows remote attackers to read unspecified data. The stack omits a required permission check while handling exceptional LTE conditions, but UNISOC has not disclosed the specific message or code path. The attacker must be within adjacent radio-network reach; exploitation requires neither prior privileges nor user interaction.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
