Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Unspecified vulnerability in Oracle Sun Solaris 11 allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Solaris Kernel Zones, a different vulnerability than CVE-2016-0414.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Local privilege escalation or kernel compromise vulnerability in Oracle Solaris 11 affecting the Kernel Zones component. The vulnerability allows a local authenticated user to impact confidentiality, integrity, and availability through unspecified vectors in the kernel, representing a different flaw than CVE-2016-0414.

MitigationApply Oracle Critical Patch Updates for Solaris 11, specifically kernel zone patches. Restrict local user privileges and monitor zone administrative access until patched.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Oracle Solaris 11 is installed
    Run `uname -a` or check `/etc/release` to identify the operating system version
    Affected if The system is not running Oracle Solaris 11 (the CVE only affects Solaris 11)
  2. Verify Kernel Zones are configured
    Run `zoneadm list -civ` to list all zones and identify if any are kernel zones (non-global zones with kernel virtualization)
    Affected if No kernel zones exist on the system (the vulnerability only affects the Kernel Zones component)
  3. Check installed Solaris 11 patch level
    Run `showrev -p` to list installed patches and compare against Oracle's patch database for CVE-2016-0418 fixes
    Affected if The system is missing the specific patch for this CVE (unpatched Solaris 11 with kernel zones)
  4. Verify local user access to the system
    Review user accounts with local access using `logins` or `/etc/passwd` to determine if untrusted local users exist
    Affected if Untrusted local authenticated users have access to a system with kernel zones enabled

The system is affected if it runs Oracle Solaris 11 with Kernel Zones configured and lacks the CVE-2016-0418 patch, allowing a local authenticated user to potentially escalate privileges or compromise the kernel.
