Local information disclosure via swpm race
Published Jun 6, 2023 · Updated Jan 7, 2025
Out-of-bounds write in swpm on MediaTek Android 13 chipsets allows local users with System privileges to disclose information via a race condition. Concurrent execution in swpm can trigger an out-of-bounds write; MediaTek has not published the affected function, buffer, or shared-resource operation. Exploitation requires local System execution privileges and high-complexity race timing without user interaction; the reported consequence is information disclosure only.
