Local code execution via out-of-bounds write
Published Dec 5, 2023 · Updated Aug 2, 2024
An out-of-bounds write in libsavsvc on Samsung Mobile Devices with Android 11 through 14 allows local users to execute arbitrary code. The library writes beyond a buffer boundary during an undisclosed operation, and Samsung has not published the affected function or input path. The attacker needs local access to an affected device; successful exploitation runs attacker-controlled code in the vulnerable component's context.
