CVE-2022-26472

Local privilege escalation via malformed IMS parcel

Published Oct 7, 2022 · Updated Aug 3, 2024

Deserialization in MediaTek Chipset IMS on Android 10.0, 11.0, and 12.0 allows local users to escalate privileges via a malformed parcel. The IMS component interprets a crafted parcel using a mismatched format, but MediaTek has not disclosed the affected function or parsing path. A low-privileged local context is required; exploitation needs no additional execution privileges or user interaction and grants higher device privileges.
