CVE-2026-35369
uutils coreutils kill System-wide Process Termination and Denial of Service via Argument Misinterpretation
CVSS Score
5.5
EPSS Score
0.0%
EPSS Percentile
0th
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.
