CVE-2018-14635
Last modified
CVE-2018-14635 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. EPSS estimates a 2.53% chance of exploitation in the next 30 days.
