Two accompanying OOB reads. All reproduced verbatim under ASan at HEAD `9f1cfdc`. (The affected metadata-parser header states \"Some portions generated by Copilot (Sonnet 4.6)\" — an AI-generated parser with an unchecked on-flash count.)","published":"2026-09-29T18:17:13.000Z","lastModified":"2026-09-29T19:17:24.000Z","status":"Awaiting Analysis","sourceIdentifier":"emo@eclipse.org","cvss":{"version":"4.0","score":8.6,"severity":"HIGH","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-787","CWE-1284"],"affected":[],"epss":{"score":0.00117,"percentile":0.01636,"date":"2026-10-27","history":[{"date":"2026-09-30","score":0.00117,"percentile":0.01481}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.12%).
