In the Linux kernel, the following vulnerability has been resolved: riscv:
Sparse-Memory/vmemmap out-of-bounds fix Offset vmemmap so that the first
page of vmemmap will be mapped to the first page of physical memory in
order to ensure that vmemmap’s bounds will be respected during
pfn_to_page()/page_to_pfn() operations. The conversion macros will produce
correct SV39/48/57 addresses for every possible/valid DRAM_BASE inside the
physical memory limits. v2:Address Alex’s comments
