CVE-2024-20048

Local information disclosure via uncaught flashc exception

Published Apr 1, 2024 · Updated Aug 1, 2024

Information disclosure in flashc on MediaTek chipsets running Android 12.0 or 13.0 allows local users with System privileges to read data. The flashc component leaves an exception uncaught and exposes information, but MediaTek has not published the triggering input, code locus, or data revealed. Exploitation requires prior System execution privileges and no user interaction; reported impact is limited to local information disclosure.
