CVE-2021-47450

CVE-2021-47450 affects the Linux kernel KVM on arm64. The issue was a mismanaged refcounting of stage-2 PGD pages in protected mode: the host stage-2 PGD is treated as a single compound page, which could cause tail page refcounts to drop to zero and corrupt the page-table. The fix adds hyp_split_...
