Linux Distros Unpatched Vulnerability : CVE-2026-35349

high Nessus Plugin ID 309787

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2026-35349)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
