CVE-2023-30690

Local privilege escalation via parcel mismatch

Published Oct 4, 2023 · Updated Sep 19, 2024

Improper input validation in Duo on Samsung Mobile Devices before SMR Oct-2023 Release 1 allows local users to launch privileged activities. Duo accepts mismatched parcel data without the validation needed to keep the request within its caller's privilege boundary. Local access is required, and the exposed consequence is limited to launching privileged activities; Samsung has not disclosed a narrower callable locus.
