CVE-2026-68236

The CVE concerns the Linux kernel DRM/AMD Display path. In dm_update_crtc_state(), the skip_modeset path releases the dc_stream via dc_stream_release() but fails to NULL the new_stream pointer. If a subsequent error triggers a fail path, dc_stream_release() runs again on the dangling pointer, ris...
