ImageMagick before 7.1.2-15 contains a use-after-free vulnerability in the PDB decoder that uses a stale pointer when memory allocation fails. Attackers can trigger this vulnerability by processing malicious PDB files to cause crashes or write a single zero byte to freed memory.
CVE-2026-56373
This medium-severity CVE scores 5.3 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 86% of all CVEs by exploit prediction. GitHub Security Advisory enrichment pending alignment with NVD CVSS.
- Lower severity and no public exploit yet
