Description Andrej Nemec 2017-06-02 04:54:44 EDT 
It was found that drivers/media/video/videobuf-vmalloc.c in the Linux kernel does not initialize videobuf_mapping data structures, which allows local users to trigger an incorrect count value and videobuf leak via unspecified vectors.

Upstream patch:
