Description Mauro Matteo Cascella 2026-06-29 13:16:33 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

attr before version 2.6.0 contains a symlink traversal vulnerability in the getfattr utility 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 operations to arbitrary files by substituting a symlink, leading to local privilege escalation when getfattr is invoked by a privileged process over an attacker-controlled path.
