{"id":"CVE-2026-81884","published":"2026-09-22T16:18:03.347","lastModified":"2026-09-28T13:23:45.760","description":"radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Mach-O LC_DATA_IN_CODE parser was vulnerable because the Mach-O LC_DATA_IN_CODE parser trusted dataoff and datasize and allowed a final partial record to be processed. The vulnerability is triggered by opening a crafted Mach-O file while the non-default bin.verbose option is enabled. When datasize was not a multiple of data_in_code_entry, the last iteration read beyond the allocated buffer. This can cause a heap out-of-bounds read and possible process termination; no attacker-observable memory disclosure has been demonstrated. This issue is fixed in version 6.2.0.","cvssScore":2.5,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","cwes":["CWE-125"],"vendors":["radare"],"products":["radare2"],"references":[{"url":"https://github.com/radareorg/radare2/commit/a73de09fea7516f65c14917d66113316ec7e7d6e","tags":["Patch"]},{"url":"https://github.com/radareorg/radare2/issues/26226","tags":["Exploit","Issue Tracking","Mitigation","Vendor Advisory"]},{"url":"https://github.com/radareorg/radare2/pull/26193","tags":["Patch"]},{"url":"https://github.com/radareorg/radare2/releases/tag/6.2.0","tags":["Release Notes"]},{"url":"https://github.com/radareorg/radare2/security/advisories/GHSA-c2g2-2mc7-3x5w","tags":["Patch","Vendor Advisory"]},{"url":"https://github.com/radareorg/radare2/issues/26226","tags":["Exploit","Issue Tracking","Mitigation","Vendor Advisory"]}],"exploitRefs":[{"url":"https://github.com/radareorg/radare2/commit/a73de09fea7516f65c14917d66113316ec7e7d6e","tags":["Patch"]},{"url":"https://github.com/radareorg/radare2/issues/26226","tags":["Exploit","Issue Tracking","Mitigation","Vendor Advisory"]},{"url":"https://github.com/radareorg/radare2/pull/26193","tags":["Patch"]},{"url":"https://github.com/radareorg/radare2/releases/tag/6.2.0","tags":["Release Notes"]},{"url":"https://github.com/radareorg/radare2/security/advisories/GHSA-c2g2-2mc7-3x5w","tags":["Patch","Vendor Advisory"]},{"url":"https://github.com/radareorg/radare2/issues/26226","tags":["Exploit","Issue Tracking","Mitigation","Vendor Advisory"]}],"hasPoc":true,"ai":null}
