Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=648f39454813fcb59ddac09748b65ca1c347f777



--------------------------------

commit 8d0b89398b7ebc52103e055bf36b60b045f5258f upstream.

The hfi parser, parses the capabilities received from venus firmware and
copies them to core capabilities. Consider below api, for example,
fill_caps - In this api, caps in core structure gets updated with the
number of capabilities received in firmware data payload. If the same api
is called multiple times, there is a possibility of copying beyond the max
allocated size in core caps.
Similar possibilities in fill_raw_fmts and fill_profile_level functions.
