{"id":"CVE-2026-110659","summary":"ELFIO through 3.12 NULL Pointer Dereference via relocation_section_accessor get_entry","details":"ELFIO through 3.12 contains a NULL pointer dereference vulnerability in relocation_section_accessor get_entry() that allows attackers to crash applications via an unvalidated sh_link index. 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.","modified":"2026-10-15T02:47:43.976311901Z","published":"2026-10-14T15:01:25.207Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110659.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110659.json"},{"type":"PACKAGE","url":"https://github.com/serge1/ELFIO"},{"type":"ARTICLE","url":"https://github.com/serge1/ELFIO/blob/8ae6cec5d60495822ecd57d736f66149da9b1830/elfio/elfio_relocation.hpp#L142"},{"type":"EVIDENCE","url":"https://hackmd.io/@haind-pwn/elfio-relocation-get-entry-null-deref"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110659"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/elfio-through-3.12-null-pointer-dereference-via-relocation-section-accessor-get-entry"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/serge1/elfio","events":[{"introduced":"0"},{"last_affected":"8ae6cec5d60495822ecd57d736f66149da9b1830"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.12"}],"source":"AFFECTED_FIELD"}}],"versions":["Release_3.12","Release_3.11","Release_3.10","Release_3.9","Release_3.8","Release_3.7","Release_3.6","Release_3.5","Release_3.4","Release_3.3","Release_3.2","Release_3.1","Release_3.0","Release_2.3","Release_2.2","Release_2.1","Release_2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110659.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
