    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 of this
    vulnerability can result in unauthorized ability to
    cause a hang or frequently repeatable crash (complete
    DOS) of Oracle Solaris as well as unauthorized update,
    insert or delete access to some of Oracle Solaris
    accessible data. Note: This vulnerability applies to
    Oracle Solaris on SPARC systems only. CVSS 3.1 Base
