The CrackArmor disclosure (CVSS 7.8, CVE IDs pending NVD assignment) describes a class of confused deputy vulnerabilities in the Linux AppArmor mandatory access control framework allowing unprivileged local users to escalate to root, affecting Ubuntu and other AppArmor-enabled Linux distributions. No patch was confirmed available as of the configuration date; organizations should monitor ubuntu.com/security/vulnerabilities/crackarmor and Ubuntu security mailing lists for patch availability, treat any release as an emergency change given the local root escalation impact, and prioritize detection on systems where low-privilege or multi-tenant user access exists.
