CVE-2025-24296
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 input validation in some firmware for the Intel(R) E810 Ethernet before version 4.6 may allow a privileged user to 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 confidenceImproper input validation in Intel(R) E810 Ethernet firmware before version 4.6 allows a privileged user with local access to cause a denial of service. This is a medium-severity firmware vulnerability affecting network adapter firmware.

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 E810 adapter in systemRun 'lspci | grep -i ether' or 'lspci -d 8086:' to list Intel network devices. Look for entries containing 'E810' or similar Ethernet controller.Affected if No Intel E810 adapter is found in the system, then this CVE does not apply.
-
Retrieve firmware version of E810 adapterUse 'ethtool -i <interface>' where <interface> is the network interface name (e.g., eth0, ens33f0) associated with the E810 adapter. The 'firmware-version' field shows the current firmware.Affected if Unable to retrieve firmware version indicates the adapter or driver may not be properly loaded.
-
Compare installed version to affected rangeCheck the firmware version obtained in step 2. Compare it numerically to version 4.6. Versions before 4.6 (such as 4.5, 4.4, etc.) are affected. Versions 4.6 and later are not affected.Affected if Firmware version is below 4.6 (for example, 4.5.x, 4.4.x, or earlier).
-
Verify local privileged access scopeReview system access controls and user permissions. Determine whether untrusted local users can obtain privileged (administrator/root) access to the system where the E810 adapter is installed.Affected if Untrusted local users can gain privileged access, making exploitation possible.
Your system is affected if an Intel E810 Ethernet adapter is present with firmware version earlier than 4.6 and untrusted local users could obtain privileged access.

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 · scopedUpgrade Intel E810 Ethernet firmware to version 4.6 or later to remediate this vulnerability. Follow standard change management procedures for firmware updates.
Intel E810 Ethernet firmware version 4.6 or later
- 1. Identify the current firmware version of the Intel E810 Ethernet adapter using Intel's Ethernet Firmware Tool (EFT) or system management interface
- 2. Navigate to the Intel support website and locate the download page for Intel E810 Ethernet firmware
- 3. Download firmware version 4.6 or later for the Intel E810 Ethernet adapter
- 4. Apply the firmware update using Intel's Ethernet Firmware Tool (EFT) or the appropriate vendor firmware update method, following Intel's standard update procedure
- 5. Verify the firmware has been successfully updated to version 4.6 or later
