Subject: [PATCH AUTOSEL 6.3 30/44] ACPICA: ACPICA: check null return of ACPI_ALLOCATE_ZEROED in acpi_db_display_objects
Date: Sun, 30 Apr 2023 22:56:18 -0400 [thread overview]
Message-ID: <20230501025632.3253067-30-sashal@kernel.org> (raw)
In-Reply-To: <20230501025632.3253067-1-sashal@kernel.org>
From: void0red <30990023+void0red@users.noreply.github.com>
[ Upstream commit ae5a0eccc85fc960834dd66e3befc2728284b86c ]
ACPICA commit 0d5f467d6a0ba852ea3aad68663cbcbd43300fd4
ACPI_ALLOCATE_ZEROED may fails, object_info might be null and will cause
null pointer dereference later.
