Description
A flaw was found in the Linux kernel's AppArmor security module. This vulnerability arises when AppArmor processes unaligned Deterministic Finite Automaton (DFA) tables, which can originate from either kernel or userspace. The unaligned memory access triggered by these tables can lead to system instability or a kernel warning, potentially resulting in a Denial of Service (DoS).
