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
In all Qualcomm products with Android releases from CAF using the Linux kernel, an incorrect length is used to clear a memory buffer resulting in adjacent memory getting corrupted.

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 memory corruption vulnerability exists in Qualcomm's Linux kernel code used in Android releases from CAF (Code Aurora Forum). The flaw involves using an incorrect length value when clearing a memory buffer, which causes the memory clearing operation to overflow into adjacent memory regions, corrupting data.

MitigationOrganizations should identify and inventory all affected Qualcomm-based Android devices, then apply vendor-supplied firmware/security patches as they become available. Until patches are deployed, network segmentation may help limit exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 runs Android
    Identify the operating system version on the device. On Android, go to Settings > About Phone > Android version
    Affected if The device does not run Android (this CVE does not apply)
  2. Verify device uses Qualcomm chipset
    Check the device specifications or use commands like 'getprop' on Android to inspect ro.product.brand, ro.hardware, or ro.board.platform properties
    Affected if The device does not use Qualcomm components (the vulnerable code is in Qualcomm's Linux kernel)
  3. Identify the kernel and CAF version
    On Android, use 'uname -a' to check kernel version, or inspect /proc/version. Check for Qualcomm CAF (Code Aurora Forum) kernel patches by examining the kernel source or /proc/version string for 'CAF' or 'Qualcomm' identifiers
    Affected if The kernel contains Qualcomm CAF code (the vulnerability exists in this specific code)
  4. Check for the vulnerable memory clearing code
    Inspect the kernel source code or binary for the flawed buffer clearing operation using incorrect length values. Look for memset or similar functions operating on memory buffers in Qualcomm's kernel modules related to the affected component
    Affected if The vulnerable code pattern is present in the kernel
  5. Review security patch level
    On Android, check Settings > About Phone > Security patch level to see the installed security update
    Affected if The security patch level is older than the CVE publication date (early 2015) and the device has not received CVE-specific patches

A defender is affected if their Android device uses Qualcomm chipset/kernel components and has not received vendor-supplied security patches addressing this memory corruption flaw.
