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
UTCB object has a function pointer called by the reaper to deallocate its memory resources and this address can potentially be corrupted by stack overflow in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wired Infrastructure and Networking in MDM9205, MDM9650, QCS605, SA6155P, SC8180X, SDA845, SDM670, SDM710, SDM845, SDM850, SDX55, SM6150, SM7150, SM8150, SM8250, SXR1130, SXR2130

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

A stack overflow vulnerability in Qualcomm Snapdragon chipsets allows corruption of a function pointer in the UTCB (User Thread Control Block) object. This pointer is invoked by the reaper (a garbage collection/cleanup process) to deallocate memory resources, and when corrupted could enable arbitrary code execution.

MitigationApply vendor-supplied firmware/security patches from Qualcomm and device OEMs; network-level filtering may provide interim protection against exploitation vectors that trigger the stack overflow.

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 chipset model in use
    Examine system information via /proc/cpuinfo, device tree bindings, bootloader output, or modem AT command responses (such as AT+CGMM) to determine the specific Qualcomm chipset present
    Affected if The chipset matches any of these models: Mdm9205, Mdm9650, Qcs605, Sa6155p, Sc8180x, Sda845, Sdm670, or Sdm710
  2. Determine the firmware version of the Qualcomm chipset
    Query the firmware version through vendor-specific interfaces such as AT commands (for modems), /sys filesystem entries, bootloader information, or Qualcomm's diagnostic tools like QPST or QXDM
    Affected if The firmware version is any version of the affected chipsets listed (all versions are vulnerable)
  3. Confirm the reaper/garbage collection subsystem is active
    Verify the reaper process (cleanup/garbage collection for memory resources) is enabled in the firmware configuration. This is typically a default system service on affected chipsets.
    Affected if The reaper subsystem is present and operational, which is standard on these firmware builds

If the device uses any of the listed Qualcomm chipset models (Mdm9205, Mdm9650, Qcs605, Sa6155p, Sc8180x, Sda845, Sdm670, Sdm710) with any firmware version and has the reaper subsystem active, the environment is affected by this vulnerability.
