CVE-2026-93586

Process crash via stale ImagesToBlob pointer

Published Sep 18, 2026 · Updated Sep 18, 2026

Use-after-free in ImageMagick before 7.1.2-31 and before 6.9.13-56 allows local users to crash the affected process via ImagesToBlob. ImagesToBlob fails to update a pointer after its referenced memory is freed, so later use accesses the freed allocation. Triggering the flaw requires local access and high-complexity conditions; the documented consequence is a crash, with no confidentiality or integrity impact.
