CVE-2026-47326: Ubuntu Linux kernels leak memory when handling large AppArmor messages
CVE-2026-47326 · published 5 months ago
Summary
The Ubuntu 6.8, 6.17 and 7.0 kernel packages include a patch that can waste memory when they process very large AppArmor notifications. An ordinary user on the system could cause this, eventually using up the server's memory and slowing or stopping services. Apply the latest kernel updates from Ubuntu to get the fix and avoid resource exhaustion.
