CVE-2021-30162

Local content-provider access-control bypass via ISMS services

Published Apr 6, 2021 · Updated Aug 3, 2024

Access-control bypass in LG mobile devices running Android 4.4 through 11 allows local users to access restricted provider content. The ISMS services fail to enforce access controls for requests to specific content providers; LG has not disclosed the responsible interface or validation error. Exploitation requires local low-privileged access and permits unauthorized reading and modification of provider-managed content without interrupting device availability.
