Android 13 QPR2 Beta 1 came out on December 12th. This included backports of the ARM Mali GPU driver security along with a separate update to r38p1. GrapheneOS shipped these for the kernel driver. We had already done earlier work on updating the Mali GPU kernel drivers, but it's a lot more difficult for us because ARM doesn't make the standalone security patches available to the public and we don't currently have partner access to obtain them directly. We can ship them once Google or another vendor publishes the code. Generally, this will mean we can ship them once the next Android quarterly release Beta becomes available because they ship kernel patches months early in quarterly releases.
