Last modified

CVE-2026-35349 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. A vulnerability in the rm utility of uutils coreutils allows a bypass of the --preserve-root protection. The implementation uses a path-string check rather than comparing device and inode numbers to identify the root directory. EPSS estimates a 0.18% chance of exploitation in the next 30 days.

Description

A vulnerability in the rm utility of uutils coreutils allows a bypass of the --preserve-root protection. The implementation uses a path-string check rather than comparing device and inode numbers to identify the root directory. An attacker or accidental user can bypass this safeguard by using a symbolic link that resolves to the root directory (e.g., /tmp/rootlink -> /), potentially leading to the unintended recursive deletion of the entire root filesystem.
