CVE-2018-1094
The ext4fillsuper function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service ext4xattrinodehash NULL pointer dereference and system crash via a crafted ext4 image...
CVE-2018-1093
CVE-2018-1093 affects the Linux kernel (ext4) where ext4_valid_block_bitmap() in fs/ext4/balloc.c can trigger an out-of-bounds read due to missing validation of bitmap block numbers in balloc.c/ialloc.c. The issue allows a local attacker who can mount a crafted ext4 image to cause a denial of ser...
CVE-2018-1093
The ext4validblockbitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service out-of-bounds read and system crash via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers...
CVE-2018-1095
CVE-2018-1095 concerns the Linux kernel up to 4.15.15, where ext4_xattr_check_entries in fs/ext4/xattr.c fails to validate xattr sizes, causing misinterpretation of a size as an error code. This can enable a crafted ext4 image to trigger a get_acl NULL pointer dereference and crash the system, i....
CVE-2018-1095
The ext4xattrcheckentries function in fs/ext4/xattr.c in the Linux kernel through 4.15.15 does not properly validate xattr sizes, which causes misinterpretation of a size as an error code, and consequently allows attackers to cause a denial of service getacl NULL pointer dereference and system...

CVE-2018-1094
CVE-2018-1094 affects the Linux kernel ext4 subsystem: the ext4_fill_super routine in fs/ext4/super.c up to version 4.15.15 does not reliably initialize the crc32c checksum driver, enabling a crafted ext4 image to trigger a NULL pointer dereference in ext4_xattr_inode_hash and cause a denial of s...
CVE-2018-1092
CVE-2018-1092 : Linux kernel ext4 mounting a crafted ext4 image can trigger a NULL pointer dereference in ext4_iget, causing denial of service. This vulnerability is confirmed in multiple advisories (e.g., Debian/Ubuntu RedHat CLIs) and is addressed by applying vendor kernel updates to fixed vers...
