CVE-2026-53312

The CVE-2026-53312 issue affects the Linux kernel in the iommu/riscv invalidation path. The root cause is integer overflow when handling sign-extended page tables (ULONG_MAX) that could lead to an infinite loop during invalidation. The patch removes these overflows and relocates the +1 to avoid l...
