The company estimates more than 12 million enterprise Linux systems could be affected, including deployments running Ubuntu, Debian and SUSE.<\/p>\n<p>According to the disclosure, the vulnerabilities involve a \u201cconfused deputy\u201d scenario, where an attacker can manipulate trusted system processes into performing actions on the attacker\u2019s behalf. Qualys said the flaws could enable local privilege escalation to root, container escapes and system crashes.<\/p>\n<p>Qualys also flagged sectors it believes are likely to be impacted because of the prevalence of Linux in production environments, including cloud computing, banking and finance, manufacturing, healthcare, telecommunications, and government and defence.<\/p>\n<p>The company said kernel patching is required to address the issues.
