CVE-2026-35353
uutils coreutils mkdir Permission Exposure Race Condition with -m
CVSS Score
3.3
EPSS Score
0.0%
EPSS Percentile
0th
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.
