Quick assessment

Affected
OnePlus OxygenOS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

一加（OnePlus）OxygenOS 操作系统在 Android 平台上存在“暴露危险方法或函数”以及“授权控制不当”的漏洞。其中，olc2 日志硬件抽象层（HAL）暴露了一个 Binder 方法，该方法会调用 fork() 并执行 execl("/vendor/bin/sh", "sh", "-c", cmd, NULL)，其中 cmd 为由调用方提供的命令字符串。该接口唯一的授权检查是验证 getCallingUid() 是否等于 0（即 root 权限）。由于 SELinux 策略允许广泛客户端属性访问此

Vulnerability Title
OnePlus OxygenOS exposed dangerous method vulnerability

Vulnerability 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.
