Local information disclosure via incorrect bounds check
Published Jan 4, 2022 · Updated May 22, 2025
Information disclosure in MediaTek libMtkOmxGsmDec on Android 10.0 and 11.0 allows local users to read memory through decoder input. The library applies an incorrect bounds check to input before accessing memory, exposing data outside the intended buffer; the specific function and input field are undisclosed. A local low-privileged user can trigger the flaw without user interaction, and the documented impact is limited to confidentiality.
