Detailsinfo

A vulnerability classified as problematic has been found in Uutils coreutils up to 0.6.x. Affected is an unknown functionality of the file /dev/null of the component Cp Utility. The manipulation with an unknown input leads to a name resolution vulnerability. CWE is classifying the issue as CWE-706. The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. This is going to have an impact on integrity, and availability. CVE summarizes:

The cp utility in uutils coreutils, when performing recursive copies (-R), incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are destroyed (e.g., /dev/null becomes a regular file). This behavior can lead to runtime denial of service through disk exhaustion or process hangs when reading from unbounded device nodes.

The weakness was published by Zellic. The advisory is available at github.com. This vulnerability is traded as CVE-2026-35358 since 04/02/2026. The exploitability is told to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit.

Upgrading to version 0.7.0 eliminates this vulnerability.
