CVE-2024-22015
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 for some Intel(R) DLB driver software before version 8.5.0 may allow an authenticated user to potentially 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 DLB driver software before version 8.5.0 contains an improper input validation vulnerability that allows an authenticated local user to potentially cause a denial of service. The issue is in the driver code itself and requires local access to exploit.

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 DLB driver installationSearch for the Intel DLB driver on the system using package manager queries (dpkg, rpm, yum), driver enumeration tools, or file system searches for 'dlb' driver files. Common locations include /lib/modules/*/kernel/drivers and /opt/intel.Affected if The Intel DLB driver is installed on the system.
-
Determine installed DLB driver versionQuery the driver version via modinfo (if a kernel module), or check version metadata in driver package files, installed software inventory, or driver manifest. Use commands like 'modinfo dlb' or review driver package details.Affected if A version number is returned that is lower than 8.5.0.
-
Verify driver is loaded or activeCheck if the DLB driver kernel module is currently loaded using 'lsmod | grep dlb' or verify the driver service/daemon is running if applicable.Affected if The driver is currently loaded into the kernel or active as a service.
-
Confirm local user access existsReview system user accounts and authentication to determine whether untrusted local users have authenticated access to the system. Check for non-privileged local accounts that could exploit the vulnerability.Affected if Non-administrative local user accounts exist on the system.
The system is affected if the Intel DLB driver is installed with a version lower than 8.5.0 and is currently loaded or active, allowing authenticated local users to trigger the improper input validation flaw.

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 Intel DLB driver software to version 8.5.0 or later to remediate this vulnerability.
Intel(R) DLB driver software version 8.5.0 or later
- 1. Identify the current version of Intel(R) DLB driver software installed on the system
- 2. Navigate to the Intel website or your system's driver update mechanism
- 3. Download Intel(R) DLB driver software version 8.5.0 or later
- 4. Install the updated driver following Intel's installation instructions
- 5. Verify the installation by confirming the driver version is 8.5.0 or higher
