Prior to 13.0.0, Pillow can double free image memory when ImagingScaleAffine encounters a selective allocation failure. The affected fast path handles Transform.EXTENT or pure scale-and-translate Transform.AFFINE operations with the default NEAREST resampling. The output image allocation must succeed while the additional per-column lookup allocation fails, after which the error path deletes image storage that later cleanup releases again. An attacker who can drive such a large Image.transform() operation under memory pressure may trigger the failure. This can crash the process and may corrupt memory. This issue is fixed in version 13.0.0.","state":0,"publishedAt":"2026-10-19T21:18:57.027+00:00","modifiedAt":"2026-10-19T21:37:35.12+00:00","affected":[{"ecosystem":"Vendor product","name":"Pillow","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"python-pillow\",\n                    \"product\": \"Pillow\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 13.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/python-pillow/Pillow/security/advisories/GHSA-7mwm-ghpf-9vrm","https://github.com/python-pillow/Pillow/commit/aafa6c75f7cdabb9f409a8aac7c780bea31d08d9","https://github.com/python-pillow/Pillow/releases/tag/13.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112402","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112402","identifiers":["CVE-2026-112402"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
