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 · uneditedHEVC Video Extensions Remote Code Execution Vulnerability
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 confidenceThis is a remote code execution vulnerability in Windows HEVC Video Extensions (the codec for H.265 video playback). An attacker can exploit this by persuading a user to open a specially crafted HEVC video file, leading to arbitrary code execution with the user's privileges. The vulnerability stems from improper memory handling in the video codec.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify HEVC Video Extensions are installedOpen PowerShell and run: Get-AppxPackage -Name Microsoft.HEVCVideoExtension* | Select-Object Name, VersionAffected if The package is not found or no results returned means the extension is not installed and not affected
-
Confirm the installed version numberIf the package is found, note the Version field from the output of the previous commandAffected if Unable to retrieve a version number means the installation may be corrupted or non-standard
-
Compare version against vulnerable rangeCompare the installed version to 1.0.50361.0 - versions lower than 1.0.50361.0 are vulnerable (e.g., 1.0.50242.0, 1.0.49006.0)Affected if Installed version is less than 1.0.50361.0 indicates the environment is vulnerable
-
Check if HEVC video handling is activeThe vulnerability triggers when opening a specially crafted HEVC video file - no special configuration needs to be enabled beyond having the extension installedAffected if HEVC Video Extensions are installed with a vulnerable version and the user can open video files means the system is exploitable
User is affected if Microsoft HEVC Video Extensions are installed with a version lower than 1.0.50361.0, as the vulnerability triggers when processing HEVC video files.
