CVE-2026-54371 is a symlink traversal vulnerability in the getfattr and setfattr utilities in attr before version 2.6.0. During directory hierarchy traversal, the utilities construct and access full pathnames. A local attacker controlling a pathname component can replace a directory with a symbolic link, redirecting privileged extended-attribute operations to arbitrary files. Exploitation can cause local privilege escalation when a privileged process invokes the utilities on an attacker-controlled path. Related recursive traversal flaws also affect the getfacl, setfacl, and chacl utilities, and unsafe pathname resolution can occur during backup restoration.
