{"id":"CVE-2026-110597","summary":"Tinyexr through 3.2.0 Heap Out-of-Bounds Read via ParseEXRMultipartHeaderFromMemory","details":"Tinyexr through 3.2.0 contains a heap out-of-bounds read vulnerability in ParseEXRMultipartHeaderFromMemory() that allows attackers to read beyond buffers due to a stale remaining-size value. Attackers can supply a crafted multi-part EXR file whose later part headers bypass ReadAttribute() bounds checks, crashing applications or leaking adjacent heap memory into attribute values.","modified":"2026-10-15T02:47:24.262534814Z","published":"2026-10-14T14:16:40.331Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110597.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110597.json"},{"type":"PACKAGE","url":"https://github.com/syoyo/tinyexr"},{"type":"ARTICLE","url":"https://github.com/syoyo/tinyexr/blob/6f470c9ab24bf3992bc512ce07e8ecb00d9bf105/tinyexr.h#L10551-L10621"},{"type":"ARTICLE","url":"https://github.com/syoyo/tinyexr/blob/6f470c9ab24bf3992bc512ce07e8ecb00d9bf105/tinyexr.h#L1207-L1266"},{"type":"ADVISORY","url":"https://hackmd.io/@haind-pwn/tinyexr-multipart-header-stale-size-oob-read"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110597"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/tinyexr-through-3.2.0-heap-out-of-bounds-read-via-parseexrmultipartheaderfrommemory"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/syoyo/tinyexr","events":[{"introduced":"0"},{"last_affected":"6f470c9ab24bf3992bc512ce07e8ecb00d9bf105"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.2.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.2.0","v3.1.0","v3.0.0","v1.0.13","v1.0.12","v1.0.11","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.9.5","v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110597.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
