Subject: [PATCH 4.15 030/105] pinctrl: samsung: Validate alias coming from DT
4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzk@...nel.org>
commit 93b0beae721b3344923b4b8317e9d83b542f4ca6 upstream.
Driver uses alias from Device Tree as an index of pin controller data
array. In case of a wrong DTB or an out-of-tree DTB, the alias could be
outside of this data array leading to out-of-bounds access.
Depending on binary and memory layout, this could be handled properly
(showing error like "samsung-pinctrl 3860000.pinctrl: driver data not
available") or could lead to exceptions.
Reported-by: Geert Uytterhoeven <geert@...ux-m68k.org>
Cc: <stable@...r.kernel.org>
Fixes: 30574f0db1b1 ("pinctrl: add samsung pinctrl and gpiolib driver")
