CVE-2018-14612

CVE-2018-14612 affects the Linux kernel (through 4.17.10) with an invalid pointer dereference in btrfs_root_node() when mounting a crafted btrfs image. The root cause is lack of validation in btrfs_read_block_groups (fs/btrfs/extent-tree.c) and missing empty-tree checks in check_leaf (fs/btrfs/tr...

CVE-2018-14609

CVE-2018-14609 affects the Linux kernel (up to 4.17.10) with an invalid pointer dereference in __del_reloc_root() of fs/btrfs/relocation.c when mounting a crafted Btrfs image. The issue is triggered by removing reloc rb_trees when reloc control has not been initialized, leading to potential denia...

An issue was discovered in the Linux kernel through 4.17.10. There is out-of-bounds access in writeextentbuffer when mounting and operating a crafted btrfs image, because of a lack of verification that each block group has a corresponding chunk at mount time, within btrfsreadblockgroups in...

CVE-2018-14610

CVE-2018-14610 concerns the Linux kernel up to 4.17.10. A crafted btrfs image mounting scenario can trigger an out-of-bounds access in write_extent_buffer() due to insufficient verification that each block group has a corresponding chunk at mount time (in fs/btrfs/extent-tree.c). This can lead to...

CVE-2018-14612

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

CVE-2018-14611

CVE-2018-14611 affects the Linux kernel up to version 4.17.10. The vulnerability is a use-after-free in try_merge_free_space() when mounting a crafted Btrfs image, caused by missing chunk type flag checks in fs/btrfs/volumes.c via btrfs_check_chunk_valid . In the provided connected documents, Nes...
