CVE-2018-14612
Published: 27 July 2018
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.
From the Ubuntu Security Team
Wen Xu and Po-Ning Tseng discovered that btrfs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service (system crash).
