A small but important defensive patch landed in the Linux kernel in mid‑December 2025 that fixes a crash in the AMD DRM display stack: CVE‑2025‑68196 addresses a race where the display code could reference dc->current_state while calling into dc_update_planes_and_stream during link training (LT)...

Microsoft's public attestation narrows the immediate scope to the Azure Linux distribution, but the underlying vulnerability—an out-of-bounds access in the Linux kernel's AMD display stack—exists in upstream kernel code and therefore can appear in any product that ships a Linux kernel build with...
