MEDIUM 5.5EPSS 2.59%
Does this matter?
Lower severity and a low EPSS score (2.59%). Track it; it rarely justifies an emergency change on its own.
Description
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.
