CVE-2026-110659— ELFIO through 3.12 NULL Pointer Dereference via relocation_section_accessor get_entry

Quick assessment

Affected
serge1 ELFIO
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 ELFIO 3.12 及之前版本中，relocation_section_accessor 的 get_entry() 函数存在一个空指针解引用漏洞，攻击者可以通过未经验证的 sh_link 索引导致应用程序崩溃。攻击者可以构造一个恶意的 ELF 文件，其 SHT_REL 或 SHT_RELA 段包含一个悬空的 sh_link 字段，从而导致 find_hash_section() 解引用空指针，引发拒绝服务（DoS）攻击。

Vulnerability Title
ELFIO through 3.12 NULL Pointer Dereference via relocation_section_accessor get_entry
Source: CVE Program / CVE List V5
Vulnerability Description
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.
