How does Qualcomm patch these zero-day holes in their chipsets?
Does the company upload a firmware patch? Does the carrier? Google?

 Qualcomm provides software patches for the drivers.
 Device manufacturers have to use these patches as part of a security
update if they use the affected chipsets in their devices.

 It isn't crystal clear whether google play system updates can provide this type of fix, bypassing the manufacturer ...

It that's the case, it bypasses both the carrier & manufacturer.
I tried to look it up but what I found mostly was an old (defunct?)
amorphous project from 2020 called treble, which doesn't say much.

This person implies it's an OS release by the phone's vendor but he could
be wrong as his question applies to a prior August update & not this one.

Whatever method Qualcomm used to update Android chipset firmware, it seems
that the method used today will change later this year based on this.

More than one article echoed the sentiment that firmware updates lack
clarity in how they're being done between Qualcomm and the user's phone.
