  - Vulnerability in the Oracle Solaris product of Oracle
    Systems (component: Kernel). The supported version that
    is affected is 11. Easily exploitable vulnerability
    allows low privileged attacker with logon to the
    infrastructure where Oracle Solaris executes to
    compromise Oracle Solaris. Successful attacks require
    human interaction from a person other than the attacker.
    Successful attacks of this vulnerability can result in
    unauthorized update, insert or delete access to some of
    Oracle Solaris accessible data and unauthorized ability
    to cause a partial denial of service (partial DOS) of
    Oracle Solaris. CVSS 3.1 Base Score 3.9 (Integrity and
