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, there is a TOCTOU race condition in Secure UI.

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 · moderate confidence

This vulnerability is a Time-Of-Check to Time-Of-Use (TOCTOU) race condition存在于高通(Qualcomm)产品的安全用户界面(Secure UI)组件中,影响使用Linux内核的Android CAF(Code Aurora Forum)版本。

Mitigation应用高通和设备制造商发布的安全补丁;在补丁可用前,可考虑限制对敏感安全UI操作的访问以降低攻击面。

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 device processor vendor
    Check if the device uses a Qualcomm Snapdragon processor by looking at device specifications in Settings > About Phone > Processor or by checking /proc/cpuinfo for 'Qualcomm' or 'Snapdragon' entries
    Affected if Device does not have a Qualcomm processor - the Secure UI component is specific to Qualcomm hardware
  2. Confirm CAF build variant
    Check if the Android build is a CAF (Code Aurora Forum) variant by examining build properties: run 'getprop ro.build.version.incremental' or check /system/build.prop for CAF-specific build fingerprints
    Affected if Build is not a CAF variant - the vulnerability specifically affects CAF versions of Android with Qualcomm Secure UI
  3. Verify Secure UI component presence
    Check for the presence of Qualcomm Secure UI-related services or drivers - look for files in /vendor/lib/hw/ or /system/lib/ containing 'secureui' or check dmesg output for Secure UI kernel messages
    Affected if Secure UI component is not present on the device - the race condition only exists where this component is loaded
  4. Check kernel version and CAF tag
    Run 'uname -a' and examine the kernel version string. CAF builds typically contain 'caf' or 'msm' in the version. Also check /proc/version for Code Aurora Forum identifiers
    Affected if Kernel does not show CAF identifiers and is a stock Google/AOSP build - the vulnerability is in the CAF-specific Secure UI implementation

A user is affected if their Android device uses a Qualcomm processor with the Secure UI component AND is running a CAF (Code Aurora Forum) kernel build, as the TOCTOU race condition exists specifically in the CAF implementation of Qualcomm's Secure UI.
