As published by the source; long descriptions are shortened.

Summary A memory leak vulnerability exists in the LoadOpenCLDeviceBenchmark() function in MagickCore/opencl.c. When parsing a malformed OpenCL device profile XML file that contains <device elements without proper / closing tags, the function fails to release allocated memory for string members (platformname, vendorname, name, version), leading to memory leaks that could result in resource exhaustion. Affected Version: ImageMagick 7.1.2-12 and possibly earlier versions --- Details The vulnerability is located in MagickCore/opencl.c, function LoadOpenCLDeviceBenchmark() (lines 754-911). Root Cause Analysis: 1. When a <device tag is encountered, a MagickCLDeviceBenchmark structure is allocated (line 807-812) 2. String attributes (platform, vendor, name, version) are allocated via ConstantString() (lines 878, 885, 898, 900) 3. These strings are only freed when a / closing tag is encountered (lines 840-849) 4. At function exit (lines 908-910), only the devicebenchmark structure is freed,…

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on magick.net-q8-arm64, magick.net-q8-x86, magick.net-q16-hdri-anycpu, magick.net-q16-openmp-x64, magick.net-q16-anycpu, magick.net-q16-hdri-x86, magick.net-q16-hdri-openmp-arm64, magick.net-q16-hdri-arm64, magick.net-q16-x86, magick.net-q8-openmp-x64, magick.net-q16-hdri-openmp-x64, magick.net-q16-openmp-arm64, magick.net-q16-x64, magick.net-q8-x64, magick.net-q8-openmp-arm64, magick.net-q8-anycpu, magick.net-q16-openmp-x86, magick.net-q16-arm64, magick.net-q16-hdri-x64.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
