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."},{"lang":"es","value":"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."}],"affected":[{"source":"security@ubuntu.com","affectedData":[{"vendor":"Uutils","product":"coreutils","defaultStatus":"unaffected","collectionURL":"https://github.com/uutils","packageName":"coreutils","platforms":["Linux","Unix","macOS"],"repo":"https://github.com/uutils/coreutils","versions":[{"version":"0","lessThan":"0.6.0","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@ubuntu.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-22T17:48:28.089001Z","id":"CVE-2026-35369","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@ubuntu.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*","versionEndExcluding":"0.6.0","matchCriteriaId":"87C33018-2E08-45B0-B69C-7FC224F7F883"}]}]}],"references":[{"url":"https://github.com/uutils/coreutils/pull/9700","source":"security@ubuntu.com","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/uutils/coreutils/releases/tag/0.6.0","source":"security@ubuntu.com","tags":["Release Notes"]}]}
