CVE-2026-53312

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Remove overflows on the invalidation path Since RISC-V supports a sign extended page table it should support a gather->end of ULONG_MAX, but if this happens it will infinite loop because of the overflow. Also avoid overflow computing the length by moving the +1 to the other side of the <
