CVE-2024-0047:
NixOS vulnerability analysis and mitigation
Overview
In the Android Framework, specifically within the writeUserLP function of UserManagerService.java, a vulnerability (CVE-2024-0047) was identified where device policies are incorrectly serialized due to a logic error in the code. This vulnerability affects Android devices and was disclosed in March 2024 (NVD Dashboard).
Technical details
The vulnerability stems from a storage format issue related to user versions in Android. When upgrading from userVersion 9 (Android 13) to userVersion 10, local user restrictions were incorrectly being read as base restrictions, causing improper serialization of device policies (Android Git).
Impact
The vulnerability could potentially affect device policy management and user restrictions handling on Android devices, particularly during version upgrades from Android 13 (CIS Advisory).
Mitigation and workarounds
A fix has been implemented that properly reads the old version and converts it to the new storage format. The solution includes proper storage of device policy user restrictions and has been tested with specific test cases including 'UserRestrictionsTest' and 'UserManagerServiceUserInfoTest' (Android Git).
