Local information disclosure via incorrect bounds check
Published Jul 8, 2025 · Updated Jul 8, 2025
Out-of-bounds read in the MediaTek WLAN AP driver allows local users to disclose memory through locally executed code. An incorrect bounds check permits a read beyond the intended buffer, but MediaTek has not disclosed the affected routine or input path. User-level execution is required, while user interaction is not; the reported consequence is local information disclosure only.
