CVE-2022-26436

Local information disclosure via unchecked EMI bounds

Published Aug 1, 2022 · Updated Aug 3, 2024

Improper input validation in MediaTek Android 12 emi mpu allows local users with System privileges to disclose memory contents. The emi mpu component reads beyond the intended buffer because a missing bounds check fails to reject an out-of-range access. Exploitation requires local System execution privileges but no user interaction; the demonstrated consequence is memory disclosure only.
