The overlayfs implementation in the linux (aka Linux kernel) package before 3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions for file creation in the upper filesystem directory, which allows local users to obtain root access by leveraging a configuration in which overlayfs is permitted in an arbitrary mount namespace.

Security readout for executives and security teams

This is an Ubuntu Linux kernel local privilege escalation. A person who already has local access could abuse overlayfs permission handling to become root on affected systems. It is not remote by itself, but it can turn a low-privilege account or compromised service into full host control. Likely exposure is older Ubuntu systems through 15.04 running linux packages before 3.19.0-21.21, especially where untrusted local users, containers, or namespace-capable workloads can reach overlayfs behavior. Prioritize remediation on any remaining legacy Ubuntu hosts. The business risk is full host takeover after initial local access, which can expand the impact of a compromised account, service, or container workload. Mitigation focus: Upgrade affected Ubuntu linux packages to 3.19.0-21.21 or later.; Review Canonical guidance for release-specific fixed package versions.; Avoid permitting overlayfs in arbitrary mount namespaces where patching is delayed..
