CVE-2026-70387 · OnePlus OxygenOS exposed dangerous method vulnerability
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
