It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-81880 in the wild and no public exploit code.\n\nAffected product: Radare Radare2. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-81880/ (Markdown: https://insights.sbomify.com/CVE-2026-81880/index.md)","id":"CVE-2026-81880","markdown":"https://insights.sbomify.com/CVE-2026-81880/index.md","name":"CVE-2026-81880","record":{"aliases":["GHSA-fg6f-rj8g-25pq","UBUNTU-CVE-2026-81880"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"radare2 reverse engineering tool","requires_auth":"none","summary":"An attacker can cause denial of service in radare2 by providing a crafted Apple PEF file that triggers excessive CPU consumption during loading.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"radare2","vendor":"radare"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-834","name":"Excessive Iteration"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Apple Preferred Executable Format loader was vulnerable because the PEF loader accepted relocSecCount values that were not bounded by the number of sections or complete relocation records in the input. The vulnerability is triggered by normal binary-format auto-detection of a small crafted Apple PEF file. The loader could perform up to 268,435,456 relocation-section iterations and repeated buffer operations after record offsets passed the end of the file. This can cause denial of service through excessive CPU consumption and prolonged processing. This issue is fixed in version 6.2.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"radare2: Uncontrolled resource consumption in radare2 PEF loader","id":"CVE-2026-81880","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"radare:radare2","products":["radare:radare2"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"radare2: Heap out-of-bounds read in radare2 Mach-O Swift metadata parser","id":"CVE-2026-81881"},"packages":[],"prev":{"headline":"radare2: Heap out-of-bounds read in radare2 ELF PN_XNUM handling","id":"CVE-2026-81879"},"products":["radare2"],"published":"2026-09-22","related":[{"cvss_score":10,"headline":"Buffer Overflow and Potential Code Execution in Radare2","id":"CVE-2025-1864","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":10,"headline":"Out-of-bounds Write in radare2","id":"CVE-2025-1744","kev_date_added":null,"published":"2025-02-28"},{"cvss_score":10,"headline":"Denial of service in radare2","id":"CVE-2021-32494","kev_date_added":null,"published":"2023-07-07"},{"cvss_score":10,"headline":"Use after free in radare2","id":"CVE-2021-32495","kev_date_added":null,"published":"2023-07-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29646","kev_date_added":null,"published":"2024-12-17"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46569","kev_date_added":null,"published":"2023-10-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46570","kev_date_added":null,"published":"2023-10-28"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-25","vendors":["radareorg"]},"summary":"An attacker can cause denial of service in radare2 by providing a crafted Apple PEF file that triggers excessive CPU consumption during loading.","url":"https://insights.sbomify.com/CVE-2026-81880/"}
