The formally verified seL4 microkernel has achieved complete security proofs on the AArch64 (ARM64) architecture, extending its verified correctness guarantees beyond x86. This marks a major milestone for the seL4 project, bringing its high-assurance security properties to one of the most widely deployed processor architectures.
Background
seL4 is one of the most rigorously formally verified operating system kernels in existence, with machine-checked proofs of implementation correctness against an abstract security policy. Previous proof completeness was limited primarily to x86.
