CVE-2026-46331 AppArmor Bypass via aa-exec Profile Switching on Ubuntu
Detects attempts to modify or bypass AppArmor security profiles using utilities such as aa-complain, aa-disable, or apparmor_parser, correlated with process execution involving user namespace unsharing (e.g., via unshare or CLONE_NEWUSER/CLONE_NEWNET). This combination suggests an attacker attempting to weaken host security controls or perform a container breakout or privilege escalation by manipulating kernel-level namespaces and security policies.
