Technical description

A flaw was found in cockpit-files. A local unprivileged attacker can exploit a race condition during directory creation with owner assignment. By controlling a writable parent directory, the attacker can replace a newly created directory with a symbolic link (symlink) before the ownership change operation (chown) is applied. This allows the attacker to redirect the ownership change to an arbitrary file, potentially leading to information disclosure or unauthorized modification of sensitive files.

———A flaw was found in cockpit-files. This vulnerability allows a local attacker to exploit a timing issue, known as a symlink race condition, during privileged file operations such as changing file ownership or permissions. By manipulating directory entries and winning this race, the attacker can redirect these operations to unintended files. This could lead to unauthorized changes in file ownership and permissions on arbitrary files, potentially compromising system integrity and availability by altering system or application states or rendering services unusable.7h CVE-2026-711256.1 MED
