In Android world, there is not such thing as "has been patched". It is always A complex situation with all different OEMs, devices and versions.

The patch was committed about 3 months ago, possibly available to OEMs as binary earlier, but devices are probably just receiving these patches.

I bet at least half of all affected Android devices in the world have not got the patch yet if I am optimistic. It's probably near 80-90%.
