From e9e48b7bb9cf3b78f0305ef0144aaf61da0a83d8 Mon Sep 17 00:00:00 2001 From: Alex Hung Date: Wed, 3 Jul 2024 10:50:35 -0600 Subject: [PATCH] drm/amd/display: Increase array size of dummy_boolean [ Upstream commit 6d64d39486197083497a01b39e23f2f8474b35d3 ] [WHY] dml2_core_shared_mode_support and dml_core_mode_support access the third element of dummy_boolean, i.e. hw_debug5 = &s->dummy_boolean[2], when dummy_boolean has size of 2. Any assignment to hw_debug5 causes an OVERRUN. [HOW] Increase dummy_boolean's array size to 3. This fixes 2 OVERRUN issues reported by Coverity.
