UBUNTU-CVE-2026-35369 (CVE-2026-35369)

Vulnerability from osv_ubuntu – Published: 2026-04-22 17:16 – Updated: 2026-05-14 11:40 – Source website

Details

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.

Severity
