Security readout for executives and security teams
CVE-2013-2546 is a Linux kernel information leak. A local user with CAP_NET_ADMIN could make the crypto reporting interface disclose sensitive kernel stack memory. This is not a remote compromise by itself, but it can expose data useful for deeper attacks on affected systems. Exposure is most relevant to Linux systems running kernels through 3.8.2 or distributor kernels that included the vulnerable crypto user configuration code. The capability requirement limits reach, but CAP_NET_ADMIN is common in privileged containers, network tools, and administrative service contexts. Treat this as a hardening and legacy-kernel remediation item, not an emergency internet-wide incident. Prioritize systems with untrusted local users, privileged containers, shared hosting, or sensitive workloads because information leaks can support later compromise. Mitigation focus: Upgrade affected Linux kernels using vendor security advisories.; Confirm the upstream fix commit is present in maintained kernel builds.; Restrict CAP_NET_ADMIN to trusted users, services, and containers only..
