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
Race condition in the Radeon DRI driver for Linux kernel 2.6.8.1 allows local users with DRI privileges to execute arbitrary code as root.

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 confidence

Race condition in the Radeon DRI (Direct Rendering Infrastructure) driver for Linux kernel 2.6.8.1 allows local users with DRI privileges to execute arbitrary code as root via a time-of-check-time-of-use (TOCTOU) vulnerability.

MitigationUpgrade to a patched kernel version beyond 2.6.8.1; alternatively, restrict DRI access by limiting video group membership and device file permissions if direct rendering is not required.

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 the running kernel version
    Run 'uname -r' or 'cat /proc/version' to obtain the kernel version
    Affected if The version displayed is exactly 2.6.8.1
  2. Confirm DRI is enabled
    Check for the existence of /proc/dri/ or run 'glxinfo' and look for 'direct rendering: Yes'
    Affected if DRI is enabled and direct rendering is available
  3. Verify the Radeon DRI driver is in use
    Run 'lsmod | grep radeon' or check 'dmesg' for Radeon DRI-related messages
    Affected if The radeon DRI driver module is loaded
  4. Check if the user has DRI privileges
    Check group membership for video group (groups command) and verify access to /dev/dri/ device files
    Affected if The user is a member of the video group and has access to /dev/dri/ devices

A system is affected if it is running kernel 2.6.8.1, has DRI enabled, uses the Radeon DRI driver, and the user has DRI privileges.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to a patched kernel version beyond 2.6.8.1; alternatively, restrict DRI access by limiting video group membership and device file permissions if direct rendering is not required.
