seL4 Completes AArch64 Security Proofs

This is a meaningful infrastructure milestone: verified security is moving beyond research demonstrations toward deployable Arm systems, though the proof’s assumptions still matter.

• –Completes the AArch64 proof stack across functional correctness, integrity, and confidentiality
• –Helps contain attacks or bugs in non-critical applications before they reach critical workloads
• –Addresses architectural challenges involving VCPUs, FPUs, and register-state persistence
• –Strengthens seL4’s fit for safety-critical embedded, automotive, aerospace, and defense systems
• –Developers still need to validate hardware, compiler, boot, and unverified user-space assumptions
