An issue was discovered in the Linux kernel through 4.17.10.
MEDIUM 5.5EPSS 2.51%
Does this matter?
Lower severity and a low EPSS score (2.51%). 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 io_ctl_map_page() when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c.
