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
Integer overflow in the hpsb_alloc_packet function (incorrectly reported as alloc_hpsb_packet) in IEEE 1394 (Firewire) driver 2.4 and 2.6 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via the functions (1) raw1394_write, (2) state_connected, (3) handle_remote_request, or (4) hpsb_make_writebpacket.

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

Integer overflow in the hpsb_alloc_packet function in the Linux kernel's IEEE 1394 (Firewire) driver allows local users to trigger a denial of service via crash and potentially achieve arbitrary code execution through the raw1394_write, state_connected, handle_remote_request, or hpsb_make_writebpacket functions.

MitigationUpdate the Linux kernel to a version that includes the patched hpsb_alloc_packet function with proper integer overflow protection, or disable the IEEE 1394/Firewire driver if 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. Check kernel version
    Run 'uname -r' or 'cat /proc/version' to get the running kernel version
    Affected if The version is 2.4.0 through 2.4.11 (exact match to any of these)
  2. Verify IEEE 1394 driver is present
    Run 'lsmod | grep -E "(ieee1394|ohci1394|raw1394)"' to check if any Firewire-related kernel modules are loaded
    Affected if Any of these modules (ieee1394, ohci1394, raw1394) appear in the loaded module list
  3. Check for raw1394 device node
    Run 'ls -l /dev/raw1394' to see if the raw1394 character device exists
    Affected if The device file /dev/raw1394 exists and is accessible
  4. Confirm driver availability
    Check /proc/ksyms or use 'cat /proc/modules' to enumerate loaded kernel modules for firewire components
    Affected if The IEEE 1394 subsystem modules are listed as loaded

A system is affected if it runs a Linux kernel version 2.4.0 through 2.4.11 AND has the IEEE 1394/Firewire driver modules loaded or the raw1394 device accessible.

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

Update the Linux kernel to a version that includes the patched hpsb_alloc_packet function with proper integer overflow protection, or disable the IEEE 1394/Firewire driver if not required.
