    mkdir: -m exposes directory with umask perms before chmod (race window)

    CVE-2026-35353 · GHSA-mj6p-44ch-cq69

    Affected
    • crates.io uu_mkdir < 0.6.0
    Fixed in
    0.6.0· Vendor fix available
    Issue
    The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions (typically 0755) before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces a brief window where a directory intended to be private is accessible to other users, potentially leading to unauthorized data access. --- Zellic finding 3.48. Reported in the Zellic uutils coreutils Program Security Assessment (for Canonical, Jan 2026), audited commit 3a07ffc5a9bd4c283e75afa548ba1f1957bad242.

    Recommended action: Upgrade to 0.6.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
