A connector can be connected but not bound to\nany CRTC (e.g. after hot-plug before the next atomic commit), causing a\nkernel crash when writing to the sdp_message debugfs node.\n\nThe function also ignores the user-provided size argument and always\npasses 36 bytes to copy_from_user(), reading past the user buffer when\nsize < 36.\n\nFix both issues by:\n- Returning -ENODEV when connector->base.state or state->crtc is NULL\n- Clamping write_size to min(size, sizeof(data))\n\n(cherry picked from commit 6ab4c36a522842ff70474a1c0af2e40e50fc8300)"}], "affected": [{"product":
