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
