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
The sctp module in FreeBSD 10.1 before p5, 10.0 before p17, 9.3 before p9, and 8.4 before p23 allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted RE_CONFIG chunk.

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

The Stream Control Transmission Protocol (sCTP) module in FreeBSD contains a NULL pointer dereference vulnerability when processing a specially crafted RE_CONFIG chunk. This flaw allows remote attackers to trigger a kernel panic, resulting in a denial of service condition.

MitigationApply the appropriate FreeBSD security patches (p5 for 10.1, p17 for 10.0, p9 for 9.3, p23 for 8.4) to address the NULL pointer dereference in the sctp module, and consider filtering or rate-limiting SCTP traffic at network borders if immediate patching is not feasible.

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 FreeBSD version
    Run 'uname -r' or check /etc/os-release (if present) to determine the installed FreeBSD version
    Affected if Version matches 8.4, 9.3, or 10.1 exactly
  2. Verify SCTP module is loaded
    Run 'kldstat | grep sctp' to check if the SCTP kernel module is currently loaded
    Affected if The sctp module appears in the loaded module list (sctp syscalls, sctp_core, etc.)
  3. Check SCTP boot configuration
    Inspect /boot/loader.conf for lines containing 'sctp_load="YES"' or check /etc/rc.conf for 'sctp_enable="YES"'
    Affected if SCTP is configured to load at boot or is currently enabled on the system
  4. Verify SCTP network usage
    Run 'netstat -s -p sctp' or check if any SCTP associations exist via 'sctp_status' (if installed)
    Affected if The system is actively processing SCTP traffic or has SCTP endpoints configured

A system is affected only if it runs FreeBSD 8.4, 9.3, or 10.1 AND has the SCTP module loaded or enabled, as the vulnerability is triggered by specially crafted SCTP RE_CONFIG chunks.
