In version 1.0.0, OpenVM is vulnerable to overflow through byte decomposition of pc in AUIPC chip. A typo results in the highest limb of pc being range checked to 8-bits instead of 6-bits. This results in the if statement never being triggered because the enumeration gives i=0,1,2, when instead the enumeration should give i=1,2,3, leaving pc_limbs[3] range checked to 8-bits instead of 6-bits. This leads to a vulnerability where the pc_limbs decomposition differs from the true pc, which means a malicious prover can make the destination register take a different value than the AUIPC instruction dictates, by making the decomposition overflow the BabyBear field. This issue has been patched in version 1.1.0.","published_at":"2025-05-02T22:18:55.696000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.8,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-131"],"nvd_references":["https://github.com/openvm-org/openvm/security/advisories/GHSA-jf2r-x3j4-23m7","https://github.com/openvm-org/openvm/commit/68da4b50c033da5603517064aa0a08e1bbf70a01","https://cantina.xyz/code/c486d600-bed0-4fc6-aed1-de759fd29fa2/findings/21","https://github.com/openvm-org/openvm/blob/0f94c8a3dfa7536c1231465d1bdee5fc607a5993/extensions/rv32im/circuit/src/auipc/core.rs#L135","https://github.com/openvm-org/openvm/releases/tag/v1.1.0"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:27:07.145922Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"},{"metric":"E","name":"E","value":"P","value_label":"Physical"}]},"affected":[{"vendor_slug":"openvm-org","vendor_name":"openvm-org","product_slug":"openvm","product_name":"openvm","version_start":"= 1.0.0","version_start_inclusive":true,"version_end":"= 1.0.0","version_end_inclusive":true,"cpe23_uri":"cve5:openvm-org:openvm:= 1.0.0:= 1.0.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/openvm-org/openvm/security/advisories/GHSA-jf2r-x3j4-23m7","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/openvm-org/openvm/commit/68da4b50c033da5603517064aa0a08e1bbf70a01","source_type":"PATCH","tags":["patch"]},{"url":"https://cantina.xyz/code/c486d600-bed0-4fc6-aed1-de759fd29fa2/findings/21","source_type":"MISC","tags":[]},{"url":"https://github.com/openvm-org/openvm/blob/0f94c8a3dfa7536c1231465d1bdee5fc607a5993/extensions/rv32im/circuit/src/auipc/core.rs#L135","source_type":"MISC","tags":[]},{"url":"https://github.com/openvm-org/openvm/releases/tag/v1.1.0","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-05-02T22:18:55.696000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:46:37.370372Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:46:37.370372Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:46:37.370372Z","label":"CVSS score revised","source":"cvelistv5"}]}
