Whoever makes publicly available binary blobs are necessarily aware of all those issues and try to engineer them to be resilient enough for most environments. That's why they typically work well even though they generally have little information about the system besides from most basic ones (ISA, OS/kernel and ABI to be precise). This is significantly more difficult in Linux due to its higher variability, but not even close to impossible.
