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
A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.

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.

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.

Recommended fix High confidence

DPDK 21.11 or later (or the latest LTS release available from your distribution)

  1. 1. Identify the currently installed DPDK version using 'dpkg -l | grep dpdk' or 'rpm -qa | grep dpdk'
  2. 2. Stop all applications and services that are using DPDK (such as OVS-DPDK, VPP, or custom applications)
  3. 3. For RHEL/Enterprise Linux systems: run 'sudo dnf update dpdk' to upgrade to the latest available fixed version
  4. 4. For Debian/Fedora systems: run 'sudo apt-get update && sudo apt-get upgrade dpdk' or 'sudo dnf update dpdk' respectively
  5. 5. Verify the upgraded DPDK version meets the minimum fixed version requirement (21.11 or later) using 'dpdk-version' or by checking the package version
  6. 6. Restart the DPDK-dependent applications and services
  7. 7. Monitor system logs to ensure no residual vulnerability symptoms or errors appear
Caveat Upgrading DPDK may require recompiling applications against the new version due to API/ABI changes; test applications in staging before production deployment
