Detailsinfo

A vulnerability was found in Uutils coreutils up to 0.6.x. It has been classified as critical. This affects an unknown code block of the file /tmp/rootlink of the component Rm Utility. The manipulation with an unknown input leads to a link following vulnerability. CWE is classifying the issue as CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed by Zellic. It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-35349 since 04/02/2026. The exploitability is told to be difficult. Attacking locally is a requirement. Technical details of the vulnerability are known, but there is no available exploit.

Upgrading to version 0.7.0 eliminates this vulnerability.
