  - Vulnerability in the Oracle Solaris product of Oracle
    Systems (component: Kernel). The supported version that
    is affected is 11. Easily exploitable vulnerability
    allows unauthenticated attacker with network access via
    SMB to compromise Oracle Solaris. While the
    vulnerability is in Oracle Solaris, attacks may
    significantly impact additional products. Successful
    attacks of this vulnerability can result in unauthorized
    ability to cause a partial denial of service (partial
    DOS) of Oracle Solaris. (CVE-2020-2558)

    that are affected are 10 and 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 update, insert
    or delete access to some of Oracle Solaris accessible
    data as well as unauthorized read access to a subset of
    Oracle Solaris accessible data. (CVE-2020-2656)"
