Detailsinfo
A vulnerability, which was classified as problematic, was found in Uutils coreutils up to 0.7.x. This affects the function fts_accpath of the component Chcon Utility. The manipulation with an unknown input leads to a toctou vulnerability. CWE is classifying the issue as CWE-367. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the chcon utility of uutils coreutils during recursive operations. The implementation resolves recursive targets using a fresh path lookup (via fts_accpath) rather than binding the traversal and label application to the specific directory state encountered during traversal. Because these operations are not anchored to file descriptors, a local attacker with write access to a directory tree can exploit timing-sensitive rename or symbolic link races to redirect a privileged recursive relabeling operation to unintended files or directories. This vulnerability breaks the hardening expectations for SELinux administration workflows and can lead to the unauthorized modification of security labels on sensitive system objects.
The weakness was released by Zellic. It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-35376 since 04/02/2026. The exploitability is told to be difficult. Attacking locally is a requirement. Technical details of the vulnerability are known, but there is no available exploit.
Upgrading to version 0.8.0 eliminates this vulnerability.
