Name of the Vulnerable Software and Affected Versions: Docker Engine versions prior to 18.09

Description: The issue allows attackers to cause a denial of service by consuming dockerd memory. This can be achieved by providing a large integer in the --cpuset-mems or --cpuset-cpus values. The problem is related to files daemon/daemon unix.go, pkg/parsers/parsers.go, and pkg/sysinfo/sysinfo.go.

Recommendations: For Docker Engine versions prior to 18.09, update to version 18.09 or later to resolve the issue. As a temporary workaround, consider restricting the use of the --cpuset-mems and --cpuset-cpus options to minimize the risk of exploitation.
