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 the Solaris Secure Digital slot driver (aka sdhost) in Sun OpenSolaris snv_105 through snv_108 on the x86 platform allows local users to gain privileges or cause a denial of service (filesystem or memory corruption) via unknown vectors.

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 and denial of service vulnerability in the Sun OpenSolaris Secure Digital slot driver (sdhost) affecting x86 platform versions snv_105 through snv_108. The unspecified vulnerability allows local users to potentially gain elevated privileges or cause filesystem/memory corruption.

MitigationApply vendor patches for OpenSolaris snv_105-108 or migrate to a supported Solaris/OpenIndiana version. If patches unavailable, restrict local user access to systems running the affected sdhost driver.

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. Check OpenSolaris version
    Run 'uname -r' or 'cat /etc/release' to obtain the installed OpenSolaris version number
    Affected if The version is snv_105, snv_106, snv_107, or snv_108
  2. Verify x86 platform
    Run 'uname -m' to confirm the system is running on x86 architecture
    Affected if The platform is x86 (i386, i686, or x86_64)
  3. Check if sdhost driver is loaded
    Run 'modinfo | grep sdhost' or 'ls -la /dev/sd*' to see if the sdhost driver is present and active
    Affected if The sdhost driver is loaded and the system meets the version and platform criteria

The system is affected if it runs OpenSolaris snv_105 through snv_108 on x86 architecture with the sdhost driver loaded.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patches for OpenSolaris snv_105-108 or migrate to a supported Solaris/OpenIndiana version. If patches unavailable, restrict local user access to systems running the affected sdhost driver.
