CVE-2020-8692
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 · uneditedInsufficient access control in the firmware of the Intel(R) Ethernet 700 Series Controllers before version 7.3 may allow a privileged user to potentially enable escalation of privilege and/or 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 · moderate confidenceInsufficient access control in the firmware of Intel Ethernet 700 Series Controllers before version 7.3 allows a privileged user to potentially escalate privileges or cause denial of service via local 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 Intel Ethernet 700 Series controllers installedRun `lspci | grep -i ethernet` or check system hardware inventory to list network adapters. Look for Intel Ethernet 700 Series models such as V710, X710, Xl710, or Xxv710 variants.Affected if Any Intel Ethernet 700 Series controller (V710, X710, Xl710, Xxv710) is present in the system
-
Retrieve firmware version of the Ethernet controllerUse `ethtool -i <interface>` where <interface> is the network interface name (e.g., eth0, ens33), or use the Intel Ethernet Firmware Update Tool to query the current firmware version. Alternatively, check via `lspci -v` or system management interfaces.Affected if The displayed firmware version is lower than 7.3 (for example, 7.0, 7.1, 7.2, or any version number less than 7.3)
-
Confirm the vulnerability conditionVerify that the firmware version falls within the affected range: any version before 7.3 for the identified 700 Series model (V710 At2, X710 Tm4, X710 At2, Xxv710 Am2, Xxv710 Am1, X710 Bm2, Xl710 Bm2, Xl710 Bm1).Affected if The installed firmware version is < 7.3 for any of the affected Intel Ethernet 700 Series models
The system is affected if an Intel Ethernet 700 Series controller is installed with firmware version lower than 7.3.
