Nine CrackArmor Flaws in Linux AppArmor Enable Root Escalation, Bypass Container Isolation 


https://thehackernews.com/2026/03/nine-crackarmor-flaws-in-linux-apparmor.html
Cybersecurity researchers have disclosed multiple security vulnerabilities within the Linux kernel's AppArmor module that could be exploited by unprivileged users to circumvent kernel protections, escalate to root, and undermine container isolation guarantees.
The nine confused deputy vulnerabilities have been collectively codenamed CrackArmor by the Qualys Threat Research Unit (TRU). The cybersecurity company said the issue has existed since 2017. No CVE identifiers have been assigned to the shortcomings.
