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
Acrobat Reader versions 24.001.30365, 26.001.21651 and earlier are affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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

Adobe Acrobat Reader contains a Use After Free (UAF) memory corruption vulnerability in versions 24.001.30365, 26.001.21651 and earlier. The vulnerability allows arbitrary code execution in the context of the current user when a victim opens a specially crafted malicious PDF file, requiring user interaction for exploitation.

MitigationUpdate Adobe Acrobat Reader to version 26.001.21652 or later (for branch 26) and 24.001.30366 or later (for branch 24) to address the UAF vulnerability. Users should avoid opening untrusted PDF files until updates are applied.

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 Adobe Acrobat Reader is installed
    Check the system for Adobe Acrobat Reader installation. On Windows, look in C:\Program Files\Adobe\Acrobat or C:\Program Files (x86)\Adobe\Acrobat. On macOS, check /Applications for Adobe Acrobat Reader. Alternatively, check Windows Registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{AC76BA86-7AD7-xxxx-xxxx-xxxxxxxxxxxx}
    Affected if Adobe Acrobat Reader is not installed on the system
  2. Identify the installed version
    Locate the Adobe Acrobat Reader executable (e.g., AcroRd32.exe or Adobe Acrobat Reader.exe) and view its properties to see the File Version. On Windows, right-click the executable, select Properties, and check the Details tab. On macOS, right-click the app in Applications, select Get Info, and check the Version field.
    Affected if Unable to determine the installed version number
  3. Compare version to affected ranges
    Compare your installed version to the affected version thresholds: Adobe Acrobat Reader versions below 26.001.21662 are vulnerable. If your version starts with 24.x, versions below 24.001.30383 are also affected.
    Affected if The installed version is below 26.001.21662 (or below 24.001.30383 for the 24.x track)
  4. Determine exposure to malicious PDF files
    Assess whether users in the environment commonly open PDF files from untrusted or unknown sources. The vulnerability is triggered when a victim opens a malicious PDF file.
    Affected if Users routinely open PDF attachments from untrusted or unknown sources while using a vulnerable version

A user is affected if Adobe Acrobat Reader version is below 26.001.21662 AND the user opens PDF files from untrusted sources.

  2. 2. If running version 24.x branch: upgrade to version 24.001.30383 or later
  3. 3. If running version 26.x branch: upgrade to version 26.001.21662 or later
  4. 4. Download the fixed version from the official Adobe website at https://get.adobe.com/reader/ (for Reader) or https://get.adobe.com/acrobat/ (for Acrobat)
  5. 5. Close all running instances of Adobe Acrobat or Acrobat Reader
  6. 6. Run the installer and follow the on-screen prompts to complete the upgrade
  7. 7. Verify the installed version matches or exceeds the fixed release numbers after installation
Caveat Standard point-release upgrades typically have minimal risk; ensure compatibility with existing PDF workflows and plugins before deploying enterprise-wide
