CVE-2026-31553

CVE-2026-31553 affects the Linux kernel KVM on arm64. The issue stems from computing descriptor addresses in __kvm_at_swap_desc() using (u64 __user )hva + offset, which miscomputes when offset ≠ 0, effectively performing offset 8. The correction is to use hva + offset to obtain the correct S1/S2 ...
