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
Out-of-bounds write in usb driver prior to Firmware update Sep-2024 Release on Galaxy S24 allows local attackers to write out-of-bounds memory. System privilege is required for triggering this vulnerability.

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

An out-of-bounds write vulnerability exists in the USB driver of Samsung Galaxy S24 devices running firmware versions prior to the September 2024 release. The flaw allows a locally authenticated attacker with system-level privileges to write to memory locations outside the intended buffer boundaries, potentially leading to arbitrary code execution or system compromise.

MitigationApply the September 2024 firmware update for Galaxy S24 devices to address the vulnerability in the USB 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. Confirm device model is Samsung Galaxy S24
    Check device settings: Settings > About Phone > Model Number, or run 'getprop ro.product.model' via ADB shell
    Affected if Model number does not contain 'S24' (SM-Sxxx, SM-Gxxx, or other series)
  2. Determine installed firmware version
    Check Settings > About Phone > Software Information > Build number, or run 'getprop ro.build.version.release' and 'getprop ro.build.date.utc' via ADB shell
    Affected if Unable to determine firmware version from device settings or ADB commands
  3. Compare firmware date to September 2024 cutoff
    Compare the Build number date or ro.build.date.utc timestamp against September 2024. The September 2024 release typically has build dates starting around 2024-09-01
    Affected if Firmware build date is earlier than September 2024 or build number starts with a month prior to September 2024 (e.g., Aug, Jul, Jun 2024)
  4. Verify ADB access is available for deeper inspection
    Ensure Developer Options are enabled and USB Debugging is active. Connect device and run 'adb devices' to confirm ADB shell access
    Affected if ADB access is not available and cannot verify exact firmware version through other means
  5. Check USB driver module status (if accessible)
    Run 'ls -la /vendor/lib/modules/' or 'cat /proc/modules | grep -i usb' via ADB shell to list loaded USB-related kernel modules
    Affected if Device has ADB shell access and USB driver module exists but version cannot be cross-referenced with Samsung security bulletins

Device is affected if it is a Samsung Galaxy S24 running firmware with a build date prior to September 2024, as the out-of-bounds write vulnerability exists in the USB driver of pre-September 2024 firmware versions.

Recommended fix High confidence

Samsung Galaxy S24 September 2024 Security Update (or later)

  1. Open Settings on your Galaxy S24 device
  2. Navigate to Software update
  3. Tap on Download and install to check for the September 2024 firmware update
  4. If available, download and install the update containing the September 2024 security patch
  5. Verify the update was installed by checking Settings > Software update > Download and install - the device should show "Software is up to date"
Caveat Samsung monthly security updates typically have no breaking changes; standard practice recommends backing up important data before any system update
