Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: AppArmor: Allow apparmor to handle
 unaligned dfa tables The dfa tables can originate from kernel or userspace and 8-byte alignment isn't
 always guaranteed and as such may trigger unaligned memory accesses on various architectures. Resulting in
 the following [ 73.901376] WARNING: CPU: 0 PID: 341 at security/apparmor/match.c:316
