CVE-2023-39425
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 · uneditedImproper access control in some Intel(R) DSA software before version 23.4.33 may allow an authenticated 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 confidenceIntel Data Streaming Accelerator (DSA) software before version 23.4.33 contains an improper access control vulnerability that allows an authenticated local user to escalate privileges. The vulnerability stems from insufficient access control checks within the DSA driver/software stack, enabling a local attacker with standard user privileges to gain elevated (administrative or kernel-level) access.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if Intel DSA software is installedCheck for Intel Data Streaming Accelerator driver or Intel Driver & Support Assistant installation on the system - look for Intel DSA-related drivers, services, or software packagesAffected if Intel DSA software or Intel Driver & Support Assistant is present on the system
-
Determine installed version of Intel Driver & Support AssistantUse system inventory or software management tools to retrieve the version number of Intel Driver & Support Assistant or DSA componentsAffected if The installed version is lower than 23.4.33
-
Check if DSA driver module is loadedInspect running kernel modules or device drivers to see if the Intel DSA driver is currently loaded and activeAffected if The DSA driver is loaded and running with a version below 23.4.33
-
Verify local user access contextDetermine if standard (non-privileged) local user accounts exist on the system who could potentially exploit the access control weaknessAffected if Standard user accounts exist on a system with vulnerable DSA software installed
A system is affected if Intel DSA software or Intel Driver & Support Assistant is installed with a version lower than 23.4.33, allowing local authenticated users to potentially escalate privileges.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped23.4.33
Upgrade Intel DSA software to version 23.4.33 or later to obtain the access control fix. As this is a driver-level privilege escalation, ensure the upgrade is tested in a staging environment before production deployment.
23.4.33 or later
- Navigate to the official Intel website or Intel Driver & Support Assistant download page
- Locate and download Intel Driver & Support Assistant version 23.4.33 or later
- Close any running instances of the application
- Run the installer and follow the on-screen prompts to complete the installation
- Restart the system if prompted to ensure the update takes effect
