platform/x86: toshiba_acpi: Fix array out-of-bounds access

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Armin Wolf <W_Armin@xxxxxx>

commit b6e02c6b0377d4339986e07aeb696c632cd392aa upstream.

In order to use toshiba_dmi_quirks[] together with the standard DMI
matching functions, it must be terminated by a empty entry.

Since this entry is missing, an array out-of-bounds access occurs
every time the quirk list is processed.

Fix this by adding the terminating empty entry.
