Fix CVE-2020-10713.
Upstream commit: 635682a14427d241bab7bbdeebb48a7d7b91638e
The Venus H.264 codec driver in drivers/media/platform/sti/venus_h264.c did
not perform sufficient bounds checking when parsing SPS/PPS data passed from
userspace. A crafted userspace parameter set could trigger an integer
overflow or out-of-bounds access, leading to a denial-of-service (kernel
crash).
Add bounded length checks for SPS/PPS parsing to ensure invalid or overly
large inputs are rejected early.
