From 10.0.0 until 13.0.0, Pillow can free an invalid glyph pointer during FreeType rendering with an active stroker. If FT_Load_Glyph fails, cleanup may call FT_Done_Glyph on an uninitialized or stale glyph variable. An attacker can supply a malformed font as untrusted bytes to an application that draws text with a nonzero stroke width, forcing the glyph-load failure path. This can corrupt memory or crash the process. This issue is fixed in version 13.0.0.\n\n## Affected\n\n- `Pillow >= 10.0.0, < 13.0.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-112893)\n\nAffected packages:\n\n- `pillow >= 10.0.0, < 13.0.0`\n\nPatched in:\n\n- `pillow 13.0.0`\n\nSource: https://osv.dev/vulnerability/GHSA-j4m9-6w36-pw47\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Exploit Intelligence, Lightspeed Core, OpenShift Lightspeed, Red Hat AI Inference Server, Red Hat Ansible Automation Platform 2, Red Hat Enterprise Linux 8, … · no fix planned: Exploit Intelligence, Lightspeed Core, OpenShift Lightspeed, Red Hat AI Inference Server, … · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-112893.json)","depth":"midnight","depthScore":57,"depthScoreParts":{"impact":45.1,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":230722,"id":"CVE-2026-112893","ts":1793204067249,"field":"exploit_available","old":"false","new":"true"},{"seq":230721,"id":"CVE-2026-112893","ts":1793204067249,"field":"cvss","old":"7.5","new":"8.2"},{"seq":225838,"id":"CVE-2026-112893","ts":1792498473323,"field":"cvss","old":"8.2","new":"7.5"}]}
