Subject: [PATCH 0/5] gpu: nova-core: vbios: harden various array accesses
Date: Fri, 10 Apr 2026 17:38:49 +0900 [thread overview]
Message-ID: <20260410-fix-vbios-v1-0-bc6f71d153d6@nvidia.com> (raw)
We have some code that accesses arrays based on values from firmware.
This patch series makes a bunch of those accesses more robust. This
series only touches accesses that are not guaranteed to be safe by local
invariants - some accesses are safe due to earlier checks and I haven't
modified those.
