In the Linux kernel 4.13 through 4.16.11, ext4_read_inline_data() in fs/ext4/inline.c performs a memcpy with an untrusted length value in certain circumstances involving a crafted filesystem that stores the system.data extended attribute value in a dedicated inode.

Security readout for executives and security teams

CVE-2018-11412 is a Linux kernel ext4 filesystem bug. A crafted filesystem can trigger unsafe copying in kernel code. Business risk is highest where servers, desktops, sandboxes, or analysis systems mount untrusted ext4 images or removable media. Exposure appears limited to Linux systems running affected 4.13 through 4.16.11 kernels that mount attacker-controlled ext4 filesystems, disk images, or removable media. Vendor-maintained kernels need vendor advisory mapping. Treat as a focused patching and exposure-reduction issue, not a broad internet-facing emergency. Prioritize systems that handle untrusted filesystems, forensic images, removable media, or multi-user file-processing workflows. Mitigation focus: Identify Linux hosts running kernel 4.13 through 4.16.11.; Apply relevant vendor kernel updates from Ubuntu, Red Hat, or your distribution.; Restrict mounting of untrusted ext4 filesystems and disk images..
