CVE-2026-0055 · Severity: info · CVSS 0 · Published 2026-06-01

A vulnerability in the Android Framework's package installation service could allow a malicious application to gain elevated system privileges. By exploiting a path traversal error, an attacker can manipulate the Device Policy Controller, which is responsible for managing enterprise security policies on the device. This could lead to unauthorized access to sensitive data or administrative control without requiring any user interaction.
