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@linux-m68k.org Cc: stable@vger.kernel.org Fixes: 30574f0db1b1 ("pinctrl: add samsung pinctrl and gpiolib driver") Signed-off-by: Krzysztof Kozlowski krzk@kernel.org

---

Issue is present since first version of this driver so this should be backported as far as possible.

Tested on Odroid HC1 (Exynos5422). Tests on S3C24xx, S3C64xx, Exynos ARM64 and any other chips are highly appreciated.

Linus, I can take it through samsung/pinctrl tree and later send you again as pull request... or you can apply it directly as I do not have any other pinctrl patches queued so far. --- drivers/pinctrl/samsung/pinctrl-exynos-arm.c | 56 +++++++++++++++++++---- drivers/pinctrl/samsung/pinctrl-exynos-arm64.c | 14 +++++- drivers/pinctrl/samsung/pinctrl-s3c24xx.c | 28 ++++++++++-- drivers/pinctrl/samsung/pinctrl-s3c64xx.c | 7 ++- drivers/pinctrl/samsung/pinctrl-samsung.c | 61 ++++++++++++++++---------- drivers/pinctrl/samsung/pinctrl-samsung.h | 40 ++++++++++------- 6 files changed, 154 insertions(+), 52 deletions(-)
