HIGH · CVSS 3.1 · EPSS 41.4% (pctl 99)
Patch first
On CISA KEV — known exploited in the wild, due 2022-09-29.
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.
