An issue was discovered in the Linux kernel through 4.17.10. There is an
invalid pointer dereference in btrfs_root_node() when mounting a crafted
btrfs image, because of a lack of chunk block group mapping validation in
btrfs_read_block_groups in fs/btrfs/extent-tree.c, and a lack of empty-tree
checks in check_leaf in fs/btrfs/tree-checker.c.
