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).
