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
Buffer overflow in the niu_get_ethtool_tcam_all function in drivers/net/niu.c in the Linux kernel before 2.6.36-rc4 allows local users to cause a denial of service or possibly have unspecified other impact via the ETHTOOL_GRXCLSRLALL ethtool command.

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

Buffer overflow in the niu_get_ethtool_tcam_all function in drivers/net/niu.c in Linux kernel before 2.6.36-rc4 allows local users to cause a denial of service or possibly execute arbitrary code via the ETHTOOL_GRXCLSRLALL ethtool command.

MitigationUpgrade Linux kernel to version 2.6.36-rc4 or later, or apply the vendor-supplied patch to the niu network driver.

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. Check kernel version
    Run 'uname -r' or 'cat /proc/version' to obtain the running kernel version
    Affected if The kernel version is 2.6.36 or any version lower than 2.6.36-rc4 (e.g., 2.6.35, 2.6.34, etc.)
  2. Verify niu driver presence
    Check if the niu kernel module is loaded with 'lsmod | grep niu' or if the driver file exists at /lib/modules/$(uname -r)/kernel/drivers/net/niu.ko
    Affected if The niu driver module is loaded or the driver file exists in the kernel
  3. Check for niu network interfaces
    Run 'ip link show' or 'ifconfig -a' to list network interfaces, looking for any interface associated with the niu driver (typically named based on hardware)
    Affected if Any network interface managed by the niu driver is present and active

A system is affected if it runs a kernel version at or below 2.6.36 and has the niu network driver loaded with active network interfaces, enabling the vulnerable ETHTOOL_GRXCLSRLALL code path.

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.

From vendor data
Upgrade available Upgrade to a release after 2.6.36
Interim mitigation

Upgrade Linux kernel to version 2.6.36-rc4 or later, or apply the vendor-supplied patch to the niu network driver.
