In ServiceManager::add function in the hardware service manager, there is an insecure permissions check based on the PID of the caller. This could allow an app to add or replace a HAL service with its own service, gaining code execution in a privileged process.Product: AndroidVersions: Android-8.0 Android-8.1 Android-9Android ID: A-121035042Upstream kernel

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
