OxygenOS: Improper Neutralization of Special Elements used in an OS Command
CVE-2026-70386 is a high-severity improper neutralization of special elements used in an OS command vulnerability in OxygenOS from OnePlus, with a CVSS 4.0 base score of 8.5 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 16.0.5.1200, 15.0.0.2000 as the first without the flaw, so updating OxygenOS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.38% chance of exploitation within 30 days, higher than 73% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update OxygenOS to 16.0.5.1200 or 15.0.0.2000, whichever matches your release line, or a later version.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| OnePlus | OxygenOS | 16.0.0 up to, but not including, 16.0.5.1200; 15.0.0 up to, but not including, 15.0.0.2000 | 16.0.5.1200, 15.0.0.2000 |

Official description
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.

The underlying weakness: 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.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
