CVE-2026-54371 (GCVE-0-2026-54371)

Vulnerability from cvelistv5 – Published: 2026-06-29 12:39 – Updated: 2026-06-30 14:54 X_Open Source

Title

attr < 2.6.0 Symlink Traversal Privilege Escalation via getfattr/setfattr

Summary

attr before version 2.6.0 contains a symlink traversal vulnerability in the getfattr and setfattr utilities that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link during directory hierarchy traversal. Attackers who control a pathname component can redirect getfattr and setfattr operations to arbitrary files by substituting a symlink, leading to local privilege escalation when getfattr or setfattr is invoked by a privileged process over an attacker-controlled path.

Severity

8.4 (High)
