CVE-2026-35353

CVE-2026-35353 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. 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.. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
