This would be the kind of vulnerability that would be worth millions of dollars and used for targeted attacks and/or by state actors. It could take years to uncover (like Pegasus, which took 5 years to be discovered) or never be uncovered at all.
Probably not, if you're implying remote code execution -- it was an out of bounds READ operation, not write, causing an immediate crash. Unlikely to be useful for anything other than taking systems offline (which can certainly be useful, but is not RCE).
It was a read operation during bytecode template initialization, in a driver that reads userland memory. An out of bound read operation to load code in a driver that maps user memory can easily lead to code execution and privilege escalation: if the attacker finds a way to get the out of bound read into memory they control, they could cause the driver to load a manufactured template and inject bytecode.
It's not clear that this specific vulnerability is exploitable, but it's exactly the kind of vulnerability that could be exploited for code execution.
