CVE-2026-70387 Details
Description
Exposed dangerous method or function and Incorrect Authorization vulnerability in OnePlus OxygenOS on Android. The olc2 logging HAL exposes a binder method that fork()'s and calls execl("/vendor/bin/sh", "sh", "-c", cmd, NULL) with a caller-supplied command string. The only authorization check is getCallingUid() == 0. Because SELinux policy grants binder access to this HAL to a wide client attribute, any uid-0 process in any of those domains (including dumpstate, which is reachable from an unprivileged app via Vulnerability 1) obtains arbitrary command execution. The spawned shell lands in u:r:vendor_qti_init_shell:s0 SELinux context via a policy type_transition, a domain holding all Linux capabilities. 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.
A vulnerability allowing arbitrary command execution has been identified in OnePlus OxygenOS on Android, specifically in versions 16.1.0 prior to 16.1.10.500, 16.0.0 prior to 16.0.5.1200, and 15.0.0 prior to 15.0.0.2000. The issue arises in the olc2 logging HAL, which exposes a binder method that forks a process and executes a shell command provided by the caller. The only authorization check allows any UID-0 process to access this method. Due to a permissive SELinux policy, any process with UID 0 in the allowed domains can execute arbitrary commands, with the executed shell gaining all Linux capabilities.
OnePlus has released a patch for this vulnerability in the OnePlus 15 model as part of the OxygenOS 16.0.10.500(EX01) update. Other models are scheduled to receive the update in October 2026.
