What it is

Improper neutralization of special elements used in an OS command ('OS command injection') and Missing Authorization vulnerability in OnePlus OxygenOS on Android. Any locally installed Android application, with no permissions declared

and no user interaction beyond launching it, can execute arbitrary shell

commands as uid 0 in the u:r:dumpstate:s0 SELinux domain. Two defects

combine: (a) OnePlus's atlasservice binder interface accepts

setEvent(String8 name, String8 value) from any caller without

authorization, and (b) one event handler

(OplusAtlasLogWriter::handleEvent, matching event name

atlas_event_multimedia_audio_dumpsys) copies the caller-supplied value

into the system property oplus.audio.dumpinfo.type and starts the root

init service audiodumpinfo, which passes that property value unsanitized

to system(). This issue affects OxygenOS: from 16.1.0 before 16.1.10.500, from 16.0.0 before 16.0.5.1200, and from 15.0.0 before 15.0.0.2000.
