CVE-2026-64049

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.
