CVE-2024-39797
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 drivers for Intel(R) Ethernet Connection I219 Series before version 12.19.1.39 may allow an authenticated user to potentially enable denial of service 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 · high confidenceIntel Ethernet Connection I219 Series drivers before version 12.19.1.39 contain an improper access control vulnerability that allows authenticated local users to potentially cause a denial of service condition. The vulnerability is in the driver itself, not in the network hardware, and requires local access rather than remote exploitation.

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 Intel I219 network adapterOn Windows: Open Device Manager, expand 'Network adapters', look for 'Intel(R) Ethernet Connection I219' or similar. On Linux: Run 'lspci | grep -i ethernet' to list Ethernet controllers.Affected if The system does not have an Intel Ethernet Connection I219 adapter - if not present, this CVE does not apply.
-
Check installed driver versionOn Windows: Right-click the Intel I219 adapter in Device Manager, select Properties, go to Driver tab, note the Driver Version. Alternatively, run 'Get-NetAdapter -Name *I219* | Select-Object Name, DriverVersion' in PowerShell. On Linux: Run 'ethtool -i <interface>' where <interface> is your Ethernet adapter name.Affected if A driver version is returned - proceed to version comparison.
-
Compare against vulnerable version rangeCompare the installed driver version number to 12.19.1.39. Versions below 12.19.1.39 are affected; versions at or above 12.19.1.39 are patched.Affected if The installed driver version is less than 12.19.1.39 - the system is vulnerable to this improper access control issue.
The system is affected only if it has an Intel Ethernet Connection I219 adapter with a driver version installed that is earlier than 12.19.1.39.

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 · scopedUpdate the Intel Ethernet Connection I219 driver to version 12.19.1.39 or later to remediate this vulnerability. Organizations should prioritize updates on systems with untrusted local users.
12.19.1.39 or later for Intel(R) Ethernet Connection I219 Series
- 1. Identify the current version of the Intel(R) Ethernet Connection I219 driver installed on the system
- 2. Navigate to the Intel Download Center or Intel Support website
- 3. Search for Intel Ethernet Connection I219 drivers
- 4. Download the driver version 12.19.1.39 or later
- 5. Install the updated driver following Intel's installation instructions
- 6. Restart the system if required to complete the driver update
- 7. Verify the driver version has been updated to 12.19.1.39 or later
