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.","severity":"medium","score":4.8,"published":"2026-10-26T21:52:33.622Z","modified":"2026-10-26T21:52:33.622Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/davea42/libdwarf-code/issues/336","https://github.com/davea42/libdwarf-code","https://github.com/davea42/libdwarf-code/commit/71f04013ddc2a3c88b9e25a4162ee2824741b593","https://github.com/davea42/libdwarf-code/blob/v2.3.3/src/lib/libdwarf/dwarf_debugaddr.c#L175-L216","https://hackmd.io/@haindpwn/libdwarf-debug-addr-table-section-offset-oob-read","https://www.vulncheck.com/advisories/libdwarf-through-2.3.3-heap-out-of-bounds-read-via-dwarf-debug-addr-table"],"sources":[{"name":"CVE","id":"CVE-2026-116732","modified":"2026-10-26T21:52:33.622Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-116732"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","score":4.8},{"source":"VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","score":4.4}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T22:10:31.402Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
