Affected if Version number is less than or equal to 11.2.202.235, 11.1.115.8, or 11.1.111.9 depending on the release line
Check Adobe Flash Player version on Linux

Run command: rpm -q flash-player or dpkg -l | grep flash, or check /usr/lib/flash-plugin/ for the installation directory and read version info

Affected if Version number is less than or equal to 11.2.202.235

Upgrade available Upgrade to a release after 11.2.202.235

Interim mitigation

Update Adobe Flash Player to version 10.3.183.20 or later (Windows/Mac), 11.2.202.236 or later (Linux), or 11.1.111.10+ (Android 2.x/3.x) / 11.1.115.9+ (Android 4.x); update Adobe AIR to 3.3.0.3610 or later. Note: Adobe Flash Player reached end-of-life in December 2020 and should be removed rather than updated where possible.

Recommended fix High confidence

Adobe Flash Player 11.2.202.236 or later for Linux; Adobe AIR 3.3.0.3610 or later

1. Verify the currently installed Adobe Flash Player version by navigating to 'About Flash Player' in the Adobe website or checking the system package manager
2. For Red Hat Enterprise Linux systems, use 'rpm -q flash-plugin' to check the installed version
3. For OpenSUSE systems, use 'rpm -q flash-player' or check via YaST package manager
4. Uninstall the vulnerable Flash Player version using the system package manager (e.g., 'yum remove flash-plugin' or 'zypper remove flash-player')
5. Download the fixed Adobe Flash Player version 11.2.202.236 or later for Linux from the official Adobe archive (get.adobe.com/flashplayer)
6. Install the new package using the system package manager (e.g., 'yum install flash-plugin-11.2.202.236.x86_64.rpm' or 'zypper install flash-player-11.2.202.236.x86_64.rpm')
7. For Adobe AIR, upgrade to version 3.3.0.3610 or later
8. Verify the installation was successful by checking the new version number

Caveat Flash Player is deprecated and reached end-of-life in December 2020; consider migrating to HTML5-based alternatives

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
