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
Improper buffer restrictions in some Intel(R) System Security Report and System Resources Defense firmware may allow a privileged user to potentially enable escalation of privilege via local access.

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

This is a firmware vulnerability in Intel System Security Report and System Resources Defense components. The improper buffer restrictions allow a currently privileged user to escalate their privileges further through local access, potentially achieving administrator or root-level control on the affected system.

MitigationApply the Intel firmware update for System Security Report and System Resources Defense when available. Prioritize patching systems with local privileged users or multi-user environments.

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. Identify Intel System Security Report component presence
    Check system inventory or firmware for Intel System Security Report component. On Windows, run 'wmic product get name,version' or check BIOS/UEFI firmware details. On Linux, check 'dmidecode' output or /sys/class/dmi/id/ for Intel firmware components.
    Affected if The Intel System Security Report component is present on the system
  2. Identify Intel System Resources Defense component presence
    Check system inventory or firmware for Intel System Resources Defense component. Review BIOS/UEFI firmware versions or Intel Management Engine firmware versions that include System Resources Defense.
    Affected if The Intel System Resources Defense component is present on the system
  3. Check firmware version against Intel advisories
    Retrieve the installed firmware version through manufacturer tools (Intel Firmware Advisor, Intel Platform Update, or vendor-specific firmware tools) and compare against Intel's published fixed versions for CVE-2023-48267.
    Affected if The firmware version is lower than Intel's fixed version for this CVE
  4. Assess local user privileges
    Review local user accounts and their privilege levels using 'whoami /all' on Windows or 'id' and 'sudo -l' on Linux. Identify if multiple local users with elevated privileges exist.
    Affected if Multiple local privileged users exist or non-administrator users have partial elevated access
  5. Verify multi-user environment exposure
    Determine if the system is a multi-user system where untrusted local users could gain initial privileged access. Check terminal services, remote desktop settings, or shared system configurations.
    Affected if The system allows local access by non-administrative users in a multi-user configuration

The system is affected if it contains Intel System Security Report or System Resources Defense firmware components with versions below Intel's fixed versions and operates in a multi-user or shared-access environment where local privilege escalation is possible.
