The cgre_receive_netlink_msg function in daemon/cgrulesengd.c in cgrulesengd in the Control Group Configuration Library (aka libcgroup or libcg) before 0.37.1 does not verify that netlink messages originated in the kernel, which allows local users to bypass intended resource restrictions via a crafted message.

Security readout for executives and security teams

This is a local Linux control enforcement issue in libcgroup/cgrulesengd. A user already on the system could send a spoofed netlink message that cgrulesengd trusted, potentially escaping intended CPU, memory, or other cgroup resource limits. Most relevant to older Linux systems running libcgroup/libcg with cgrulesengd enabled, especially multi-user, shared hosting, HPC, or legacy server environments that rely on cgroup rules for resource isolation. Treat as targeted legacy exposure. Prioritize shared or multi-user Linux hosts using cgrulesengd for resource governance; single-user or non-cgrulesengd systems are lower urgency based on the provided evidence. Mitigation focus: Upgrade libcgroup/libcg to 0.37.1 or a vendor-patched package.; Apply relevant Debian, Red Hat, Fedora, or openSUSE security updates where applicable.; Check vendor advisories for distribution-specific package names and backported fixes..
