Medium [CVE-2026-54370] TOCTOU Symlink Traversal via getfacl/setfacl
CVE-2026-54370Source published Source updated
acl before version 2.4.0 contains a time-of-check to time-of-use (TOCTOU) race condition vulnerability that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link between an lstat() check and subsequent symlink-following operations such as stat(), chown(), chmod(), acl_get_file(), and acl_set_file(). Attackers who control a pathname component can redirect file access control list operations to arbitrary files when getfacl, setfacl, or chacl is invoked by a privileged process over an attacker-controlled path, resulting in local privilege escalation. By replacing a pathname component with a symbolic link between a security check and subsequent file operations, an attacker can redirect file access control list operations. Red Hat severity…
