# CVE-2026-70386

> 8.5 HIGH

## Beschreibung

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.

## Schwachstellen-Klasse

- **CWE-78** — Improper Neutralization of Special Elements used in an OS Command
  The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
- **CWE-862** — Missing Authorization
  The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
