CVE-2026-21020

Privileged function invocation via exported components

Published May 13, 2026 · Updated May 13, 2026

Improper component export in OmaCP on Samsung Mobile Devices before SMR May-2026 Release 1 allows local attackers to invoke privileged functions. OmaCP exports Android application components without the permission that should restrict callers, so untrusted local apps can invoke them. Reachability requires local code execution on an affected Android 14, 15, or 16 device; the disclosed consequence is invocation with OmaCP privileges.
