CVE-2025-68196

Kernel crash via clobbered display state iteration

Published Dec 16, 2025 · Updated Dec 16, 2025

State-management flaw in AMD display link training in Linux 6.17 through 6.17.7 allows attackers to crash the kernel. The link-training automation path iterates through current_state while dc_update_planes_and_stream can clobber that state and invalidate later references. The crash requires execution of the AMD display link-training automation path; public records do not identify a user-controlled trigger or required privilege.
