Technical Analysis
CVE-2026-109268 describes a use after free vulnerability in ImageMagick's PDF writer when handling CMYK images compressed with JPEG2000. Specifically, in versions prior to 6.9.13-57 and 7.x prior to 7.1.2-32, crafted CMYK images can trigger reuse of freed memory during PDF writing, leading to process crashes. The CVSS v3.1 base score is 3.7, reflecting a network attack vector with high attack complexity and no privileges or user interaction required. The vulnerability affects availability only, with no confidentiality or integrity impact reported.
Potential Impact
The vulnerability can cause denial of service by crashing the ImageMagick process when processing maliciously crafted CMYK images with JPEG2000 compression in PDF writing. There is no indication of confidentiality or integrity compromise. No known exploits are reported in the wild.
Mitigation Recommendations
A fix is available in ImageMagick versions 6.9.13-57 and 7.1.2-32 and later. Users should upgrade to these or newer versions to remediate the vulnerability. Since this is a use after free leading to process crash, upgrading to patched versions is the recommended mitigation.
