In the Linux kernel, the following vulnerability has been resolved:
ASoC: tegra: tegra210_ahub: Validate written enum value
tegra_ahub_put_value_enum() reads e->values[item[0]] before checking whether item[0] is within the enum item range. The existing check therefore happens too late to prevent an out-of-range read of the values array.
Move the check before the array access.
