In the Linux kernel, the following vulnerability has been resolved: drm/msm/adreno: fix userspace-triggered crash on a2xx-a4xx Before a5xx Adreno driver will not try fetching UBWC params (because those generations didn't support UBWC anyway), however it's still possible to query UBWC-related params from the userspace, triggering possible NULL pointer dereference. Check for UBWC config in adreno_get_param() and return sane defaults if there is none. Patchwork: https://patchwork.freedesktop.org/patch/717778/
