CVE-2026-35369
Last modified
CVE-2026-35369 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
Description
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.
