Summary

The gnss component in MediaTek chipsets MT2737, MT6813, MT6980D, MT6982, MT6986 and other models is affected. A missing bounds check allows an out-of-bounds write (CWE-787). A local user needs no additional execution privileges, but user interaction is required, and exploitation can cause a local denial of service.
