A security issue has been reported in LVM2, which can be exploited by malicious, local users to perform certain actions with escalated privileges.
The security issue is caused due to usage of an abstract socket for communication between lvm and clvmd without checking for credentials. This can be exploited to instruct the "clvmd" to perform operations e.g. activate, deactivate, or reload any Logical Volume.
Successful exploitation requires that "clvmd" is running.
Solution: Update to version 2.02.72.
Provided and/or discovered by: Reported by the vendor.
