CVE-2026-26158 (GCVE-0-2026-26158)

Vulnerability from cvelistv5 – Published: 2026-02-11 20:27 – Updated: 2026-02-12 15:39

Title

Busybox: busybox: arbitrary file modification and privilege escalation via unvalidated tar archive entries

Summary

A flaw was found in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by crafting a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead to privilege escalation, enabling an attacker to gain unauthorized access to critical system files.
