Android OS Privilege Escalation Vulnerability
Exploited in the wild
This vulnerability is on a Known Exploited Vulnerabilities catalogue, added 2022-09-08. Federal due date: 2022-09-29.
Apply updates per vendor instructions.
Impact
The vold volume manager daemon on Android 3.0 and 2.x before 2.3.4 trusts messages that are received from a PF_NETLINK socket, which allows local users to execute arbitrary code and gain root privileges via a negative index that bypasses a maximum-only signed integer check in the DirectVolume::handlePartitionAdded method, which triggers memory corruption, as demonstrated by Gingerbreak.
