CVE-2026-45893

In the Linux kernel, the following vulnerability has been resolved: apparmor: Fix & Optimize table creation from possibly unaligned memory Source blob may come from userspace and might be unaligned. Try to optize the copying process by avoiding unaligned memory accesses. - Added Fixes tag - Added "Fix &" to description as this doesn't just optimize but fixes a potential unaligned memory access [jj: remove duplicate word "convert" in comment trigger checkpatch warning]
