CVE-2026-110659 (GCVE-0-2026-110659)

Vulnerability from nvd – Published: 2026-10-14 15:01 – Updated: 2026-10-20 01:27

Title

ELFIO through 3.12 NULL Pointer Dereference via relocation_section_accessor get_entry

Summary

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.
