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 multiple Qualcomm Snapdragon chipsets due to missing bounds checking on array index calculations. The lack of validation on index values allows writing data beyond array boundaries, potentially leading to memory corruption, arbitrary code execution, or denial of service. This is a critical memory safety flaw in the firmware/software running on the affected SoCs.

MitigationApply firmware updates provided by device manufacturers that address this vulnerability. If no update is available, implement network-level compensating controls to limit exposure of affected devices and monitor for exploitation attempts.

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 Qualcomm Snapdragon chipset in use
    On Android devices, run 'getprop ro.board.platform' or check /proc/cpuinfo. For embedded/IoT devices, consult hardware documentation, schematics, or FCC ID filings.
    Affected if The chipset matches any of: Apq8009, Apq8017, Apq8053, Apq8076, Apq8096, Apq8096au, Apq8098, or Mdm9150
  2. Confirm the firmware version
    On Android: 'getprop ro.build.description' or check /proc/version. For other embedded systems: consult vendor documentation or check bootloader/Baseband version via 'dmesg' or AT commands if applicable.
    Affected if Any firmware version is returned for a chipset in the affected list - note that all versions of these chipsons are vulnerable.
  3. Check device vendor documentation
    Review the device or system integrator documentation to verify the specific SoC model and firmware version implemented.
    Affected if Documentation confirms use of any affected chipset listed in the CVE.
  4. Inspect system logs for memory corruption indicators
    Review kernel logs (dmesg) and system crash logs for out-of-bounds write errors, memory corruption, or unexpected kernel panics related to array index operations.
    Affected if Logs show unexplained memory corruption or crashes that could indicate exploitation of this flaw.

A system is affected if it embeds or runs firmware on any of the listed Qualcomm chipsets (Apq8009, Apq8017, Apq8053, Apq8076, Apq8096, Apq8096au, Apq8098, Mdm9150), regardless of firmware version.
