CVE-2026-35369

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.

Summary		(es) Un error de análisis de argumentos en la utilidad kill de uutils coreutils interpreta incorrectamente kill -1 como una solicitud para enviar la señal predeterminada (SIGTERM) al PID -1. Enviar una señal al PID -1 hace que el kernel termine todos los procesos visibles para el llamador, lo que podría llevar a una caída del sistema o a una terminación masiva de procesos. Esto difiere de GNU coreutils, que reconoce correctamente -1 como un número de señal en este contexto y en su lugar informaría un argumento PID faltante.
