Please set this advisory's CVE ID to CVE-2026-56367. The CVE ID field is not editable in this form, so this suggestion only adds that CVE record to References.

The current alias, CVE-2026-25984, was rejected by its CNA (GitHub_M) on 2026-02-23 with the reason "This CVE was assigned in error" (https://cveawg.mitre.org/api/cve/CVE-2026-25984). The ImageMagick repository advisory lists no CVE.

CVE-2026-56367 (VulnCheck, published 2026-06-21, https://cveawg.mitre.org/api/cve/CVE-2026-56367) cites GHSA-273h-m46v-96q4 and describes the same integer overflow in ReadPSDChannelRLE (coders/psd.c): a heap out-of-bounds read on 32-bit builds, fixed in 7.1.2-15 and 6.9.13-40.

Today CVE-2026-56367 sits only on the unreviewed GHSA-rg39-4fm5-hrp2, which lists no package, so a lookup by CVE-2026-56367 finds none of the 19 Magick.NET packages. Once this advisory carries the CVE, GHSA-rg39-4fm5-hrp2 could probably be withdrawn as a duplicate, and the NVD reference to CVE-2026-25984 updated.

Found in a pre-registered study: https://github.com/munimtechnologies/advisory-import-census/blob/main/study/second-cve-s5/RESULTS.md Checked with public APIs on 2026-11-01.

We don't want to assign the CVE that was provided. We did not request this so don't add it.
