CVE-2026-35361 Details
Description
The mknod utility in uutils coreutils fails to handle security labels atomically by creating device nodes before setting the SELinux context. If labeling fails, the utility attempts cleanup using std::fs::remove_dir, which cannot remove device nodes or FIFOs. This leaves mislabeled nodes behind with incorrect default contexts, potentially allowing unauthorized access to device nodes that should have been restricted by mandatory access controls.
A vulnerability exists in the mknod utility of uutils coreutils, specifically in version 0.6.0, related to the management of security labels. The issue arises because the utility creates device nodes before applying the appropriate SELinux context. If the labeling process fails, mknod attempts to remove the incorrectly labeled node using a directory removal command that cannot handle device files or FIFOs. This flawed cleanup leaves behind device nodes with incorrect labels, potentially granting unauthorized access to nodes that should be protected by mandatory access controls.
Users can update to the latest version of uutils coreutils, where this issue has been addressed.
