EPSS Score41.4%

EPSS (Exploit Prediction Scoring System) estimates a 41.4% chance this CVE is exploited in the wild within the next 30 days — higher than 99% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

The vold volume manager daemon in Android kernel trusts messages from a PF_NETLINK socket, which allows an attacker to execute code and gain root privileges. This vulnerability is associated with GingerBreak and Exploit.AndroidOS.Lotoor.

Description

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.
