Attackers can supply a crafted ELF file whose SHT_REL or SHT_RELA section has a dangling sh_link, causing find_hash_section() to dereference null and deny service.","state":0,"publishedAt":"2026-10-14T15:01:25.207+00:00","modifiedAt":"2026-10-20T01:27:15.189+00:00","affected":[{"ecosystem":"https://github.com/serge1/ELFIO","name":"ELFIO","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"serge1\",\n                    \"product\": \"ELFIO\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThanOrEqual\": \"3.12\"\n                        }\n                    ],\n                    \"collectionURL\": \"https://github.com/serge1/ELFIO\",\n                    \"repo\": \"https://github.com/serge1/ELFIO\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.8,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.5,"severity":"MEDIUM"}],"references":["https://hackmd.io/@haind-pwn/elfio-relocation-get-entry-null-deref","https://github.com/serge1/ELFIO/blob/8ae6cec5d60495822ecd57d736f66149da9b1830/elfio/elfio_relocation.hpp#L142","https://github.com/serge1/ELFIO","https://www.vulncheck.com/advisories/elfio-through-3.12-null-pointer-dereference-via-relocation-section-accessor-get-entry"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110659","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110659","identifiers":["CVE-2026-110659"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
