  - v4l2-core: fix an issue with error handling for VIDIOC_G_CTRL;
  - vb2 core: fix an issue at vb plane copy logic;
  - videobuf2-core: copy vb planes unconditionally;
  - vivid: fix buffer overwrite when using > 32 buffers;
  - vivid: fix a potential division by zero due to an issue at v4l2-tpg;
  - some spectre vulnerability fixes;
  - several OOM access fixes;
  - some buffer overflow fixes.

Regards,
Mauro
