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
Uncontrolled Search Path Element in Arm Development Studio before 2025 may allow an attacker to perform a DLL hijacking attack. Successful exploitation could lead to local arbitrary code execution in the context of the user running Arm Development Studio.

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

Arm Development Studio before version 2025 contains an uncontrolled search path element vulnerability allowing DLL hijacking. The application loads dynamic link libraries without fully qualifying paths, enabling an attacker to place a malicious DLL in a directory searched by the application. Successful exploitation allows local arbitrary code execution with the privileges of the user running the software.

MitigationUpgrade to Arm Development Studio 2025 or later, which addresses the uncontrolled search path element. Alternatively, ensure the application runs from trusted directories and remove any untrusted locations from the system PATH that precede system directories.

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 installed Arm Development Studio version
    Locate the Arm Development Studio installation directory (commonly in C:\Program Files\Arm\ or C:\Program Files (x86)\Arm\) and check for version information in the product documentation, about dialog, or installer metadata. The version is typically displayed as a year-based release (e.g., 2024.x).
    Affected if The installed version is earlier than 2025.0 (e.g., 2024.1, 2024.0, or earlier releases).
  2. Compare version against affected range
    If version information is found, compare it to the affected range: any version before 2025.0 is vulnerable. Versions starting with 2025.0 or later are not affected.
    Affected if The installed version is < 2025.0 according to the CVE affected products list.
  3. Examine system PATH for suspicious directories
    Review the system and user PATH environment variables for any untrusted or writable directories that precede system directories (such as C:\Windows\System32). Use 'echo %PATH%' in Command Prompt or check System Properties > Environment Variables.
    Affected if The PATH contains user-writable directories (e.g., temp folders, download directories) placed before system directories, increasing DLL hijacking risk.
  4. Verify application execution context
    When Arm Development Studio is launched, observe which directories are searched for DLLs by monitoring process creation or checking the application's working directory. Ensure the working directory is a trusted location.
    Affected if The application is launched from or operates in a directory writable by untrusted users, or the working directory contains untrusted DLLs.

A user is affected if Arm Development Studio version is installed and is earlier than 2025.0, and the PATH or working directory contains untrusted locations that could be exploited for DLL hijacking.

Upgrade available Upgrade to 2025.0 or later
Fixed in 2025.0
Interim mitigation

Upgrade to Arm Development Studio 2025 or later, which addresses the uncontrolled search path element. Alternatively, ensure the application runs from trusted directories and remove any untrusted locations from the system PATH that precede system directories.

Recommended fix High confidence

2025.0

  1. Check the current installed version of Arm Development Studio
  2. Download Arm Development Studio version 2025.0 or later from the official ARM developer website (developer.arm.com)
  3. Install the new version following Arm's standard installation procedures
  4. Verify the installation completed successfully and the new version is running
