Fingerprint service disruption via TA file parsing
Published Oct 14, 2022 · Updated May 14, 2025
Memory safety flaw in Huawei HarmonyOS 2.0 and EMUI 11.0.1/12.0.0 allows local root users to disrupt fingerprint service via crafted files. The fingerprint trusted application processes attacker-controlled file content without preventing heap overflows, out-of-bounds reads, or null-pointer dereferences. Root permission is required on the phone, and exploitation can make the fingerprint service abnormal; confidentiality impact is not reported.
