The supported version that is affected is 11.4. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Solaris executes to compromise Oracle Solaris.  Successful attacks of this vulnerability can result in  unauthorized read access to a subset of Oracle Solaris accessible data. CVSS 3.1 Base Score 3.3 (Confidentiality impacts).
