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 access control in the Intel(R) Ethernet Controller RDMA driver for linux before version 1.9.30 may allow an unauthenticated user to potentially enable escalation of privilege via network 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

Improper access control in the Intel Ethernet Controller RDMA driver for Linux allows unauthenticated network attackers to potentially escalate privileges. The vulnerability exists in versions prior to 1.9.30 and could be exploited via network access to the affected interface.

MitigationUpgrade the Intel Ethernet Controller RDMA driver for Linux to version 1.9.30 or later to remediate this vulnerability.

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 if Intel Ethernet RDMA driver is present
    List loaded kernel modules or installed driver packages related to Intel network/RDMA functionality using 'lsmod' or package manager queries. Look for Intel Ethernet RDMA driver modules.
    Affected if The Intel Ethernet Controller RDMA driver is loaded or installed on the system
  2. Retrieve the installed RDMA driver version
    Query the driver version via 'modinfo' on the relevant Intel RDMA module, or check the driver package version if installed via a package manager. Compare the version number against the 1.9.30 threshold.
    Affected if The driver version is found to be lower than 1.9.30
  3. Check for active network interfaces using the affected driver
    Identify network interfaces managed by the Intel Ethernet RDMA driver using 'ip link show' or 'ip addr'. Note which interfaces correspond to the affected driver.
    Affected if There are active network interfaces using the Intel Ethernet RDMA driver and the driver version is below 1.9.30

A system is affected if the Intel Ethernet Controller RDMA driver for Linux is installed with a version lower than 1.9.30 and has active network interfaces using that driver.

Upgrade available Upgrade to 1.9.30 or later
Fixed in 1.9.30
Interim mitigation

Upgrade the Intel Ethernet Controller RDMA driver for Linux to version 1.9.30 or later to remediate this vulnerability.

Recommended fix High confidence

1.9.30

  1. Verify the current driver version by running: modinfo irdma or checking /sys/class/infiniband/*/device/driver/version
  2. Download the Intel Ethernet Controller RDMA driver version 1.9.30 or later from Intel's official support website or your Linux distribution's package repository
  3. If using a distribution package manager (apt, yum, dnf), update the driver package: sudo apt-get update && sudo apt-get install irdma (Debian/Ubuntu) or sudo yum/dnf update irdma (RHEL/CentOS)
  4. If building from source, ensure you have kernel-devel and build dependencies installed, then follow Intel's installation guide for the driver
  5. Reboot the system or unload/reload the driver module: sudo modprobe -r irdma && sudo modprobe irdma
  6. Verify the new version is loaded: modinfo irdma | grep version
