Trustlist disruption via repeated linked-list insertion
Published Oct 28, 2021 · Updated Aug 4, 2024
Race condition in EMUI 10.1.1 and 11.0.0 allows attackers to disrupt trustlist management via unspecified vectors. Concurrent trustlist updates repeatedly insert the same strings into a linked list because synchronization does not prevent competing insertion operations. Huawei has not published the trigger, required access, affected process, or whether the resulting trustlist-management exceptions persist beyond the operation.

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.
