Subject: [PATCH 38/50] drm/amd/display: Increase array size of dummy_boolean
Date: Wed, 10 Jul 2024 15:36:55 -0400 [thread overview]
Message-ID: <20240710193707.43754-39-Jerry.Zuo@amd.com> (raw)
In-Reply-To: <20240710193707.43754-1-Jerry.Zuo@amd.com>
From: Alex Hung <alex.hung@amd.com>
[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.
