Detailsinfo

A vulnerability classified as problematic was found in Uutils coreutils up to 0.5.x. This vulnerability affects an unknown part. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. CVE summarizes:

An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal (SIGTERM) to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massive process termination. This differs from GNU coreutils, which correctly recognizes -1 as a signal number in this context and would instead report a missing PID argument.

The weakness was shared by Zellic. The advisory is shared for download at github.com. This vulnerability was named CVE-2026-35369 since 04/02/2026. The exploitation appears to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available.
