svm ioctl

The svm ioctl tag covers a Linux kernel security vulnerability (CVE-2026-46197) in AMD's amdkfd GPU compute driver. The issue involves an unchecked user-controlled SVM attribute count that could lead to out-of-bounds buffer access before the ioctl handler validates the request. This vulnerability is relevant to systems running Linux kernels, including those in AI workstations, compute clusters, and Windows-adjacent environments like virtualization or dual-boot setups. The tag highlights how modern GPU drivers expand the attack surface and why even small CVEs deserve attention.
