Attackers can supply a crafted object file with a non-zero offset table, causing dwarf_debug_addr_by_index() to read past the heap buffer, disclosing adjacent heap bytes or crashing consumers.","categories":["Unclassified"],"product":"libdwarf","vendor":"davea42","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116732","source_modified_at":"2026-10-26T21:52:33.622Z","fetched_at":"2026-10-26T23:45:56.352924Z","product":"libdwarf","vendor":"davea42","versions":[{"version":"0","status":"affected","versionType":"custom","lessThanOrEqual":"2.3.3"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T21:52:33.622Z","modified_at":"2026-10-26T21:52:33.622Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116732","fetched_at":"2026-10-26T23:45:56.352924Z","source_modified_at":"2026-10-26T21:52:33.622Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/davea42/libdwarf-code/issues/336","tags":["issue-tracking"]},{"source":"CVE List","url":"https://github.com/davea42/libdwarf-code","tags":["product"]},{"source":"CVE List","url":"https://github.com/davea42/libdwarf-code/commit/71f04013ddc2a3c88b9e25a4162ee2824741b593","tags":["patch"]},{"source":"CVE List","url":"https://github.com/davea42/libdwarf-code/blob/v2.3.3/src/lib/libdwarf/dwarf_debugaddr.c#L175-L216","tags":["technical-description"]},{"source":"CVE List","url":"https://hackmd.io/@haindpwn/libdwarf-debug-addr-table-section-offset-oob-read","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/libdwarf-through-2.3.3-heap-out-of-bounds-read-via-dwarf-debug-addr-table","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T21:52:33.622Z","content_hash":"fb3ff122286e5025f0fb4808821d52f16ca9115f36fd1bef73898f894abb8bbc"}}
