Yaaay not yay, my phone has a confirmed use-after-free #vulnerability in its proprietary #GPU #firmware which #Samsung will of course not bother to fix.
The device is not even 6 years old.

On the flip side, the folks at @murena have just kindly boosted my #Samsung #GalaxyS9 from 2018 to #deGoogled #Android 12, and as always their OTA upgrade worked like a charm.

Yes, DivestOS on Google Pixel 6 and higher is using the r38 driver which is affected since it is still on A13.

I plan to try and use the newer driver for the June update.
A14 based systems should be on the newer r47.

It isn't in a proprietary firmware component, but in a kernel module. Source linked above.
