AI Agent Finds Linux Kernel Bug That Turns a Tiny Memory Write Into Root Access
Details: https://t.co/AkqjXsLYtY
CVE-2026-72018 is a high-severity Linux kernel vulnerability that converts a tightly constrained out-of-bounds memory write into local root access.
The flaw affects the DIBS loopback implementation used by the SMC-D shared-memory communication path; a missing bounds check lets attacker-controlled data be copied beyond an allocated kernel buffer.
The issue exists in the dibs_loopback driver, which enables Shared Memory Communications Direct, or SMC-D, on standard x86 Linux systems without IBM Z hardware.
