Prior to 6.2.0, radare2's Mach-O Swift field-metadata parser was vulnerable because a relative Swift field pointer could be lower than the field-metadata section base, making subtraction produce a negative logical index. The vulnerability is triggered by parsing Swift type and class metadata from a crafted Mach-O file. The derived index was used to read four bytes immediately before the allocated field-metadata buffer. This can cause incorrect metadata processing or process termination; no attacker-observable memory disclosure has been demonstrated. This issue is fixed in version 6.2.0."}], "lastModified": "2026-09-25T16:49:14.450", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:radare:radare2:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "89E67591-1BCF-49F0-B047-71FCB5524CDB", "versionEndExcluding": "6.2.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
