Service interruption via out-of-bounds devicemanager read
Published Aug 6, 2025 · Updated Aug 6, 2025
Out-of-bounds read in Huawei HarmonyOS 5.0.1 and 5.1.0 devicemanager allows remote attackers on an adjacent network to interrupt service. Huawei has not disclosed the affected function, the input that crosses a buffer boundary, or whether the read causes a crash, hang, or another interruption. Exploitation requires adjacent-network reachability but no authentication or user interaction, and no public exploit has been reported.
