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.

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 bounds checking vulnerability exists in the RX FIFO handling logic of Snapdragon chipsets where the RX FIFO write index read from shared RAM is not validated against the FIFO size before use. This missing validation allows an attacker to access memory beyond allocated buffers, resulting in heap/stack memory corruption and potential information disclosure of sensitive data from adjacent memory regions.

MitigationImplement a bounds check to verify the RX FIFO write index is less than the FIFO size before using it to access the FIFO, and deploy the firmware update through OEM channels.

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
    Check /proc/cpuinfo, /sys/devices/system/cpu/, or use 'lshw' or 'cat /proc/device-tree/model' to identify the chipset. Alternatively, check boot logs with 'dmesg | grep -i qualcomm' or review /sys/firmware/devicetree/base/model
    Affected if The chipset model matches one of the affected variants: Apq8009, Apq8017, Apq8053, Apq8096, Apq8096au, Apq8098, Ipq6018, or Ipq8074
  2. Determine the firmware version
    Check the baseband or system firmware version through vendor documentation, /proc/version, /sys/firmware/, or by contacting the device OEM. For some devices, 'cat /sys/class/net/*/device/firmware_version' or 'getprop ro.build.fingerprint' (Android) may reveal version strings
    Affected if Any firmware version is installed on an affected chipset - the advisory lists 'all versions' as vulnerable
  3. Confirm RX FIFO handling is in use
    Identify if the device uses networking or serial interfaces that rely on the Snapdragon RX FIFO handling. Check for network interface drivers or check system logs for relevant hardware initialization. This is a hardware-level IP block, so confirm the Snapdragon SoC is actively processing network traffic
    Affected if The device actively uses the Snapdragon chipset for data reception (any network I/O through the Qualcomm IP)

If the device uses any of the listed Qualcomm chipset models (Apq8009, Apq8017, Apq8053, Apq8096, Apq8096au, Apq8098, Ipq6018, Ipq8074) with any firmware version, it is potentially affected by this bounds check vulnerability in the RX FIFO handling logic.
