Описание
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (lm95234) Fix underflows seen when writing limit attributes
DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large negative number such as -9223372036854775808 is provided by the user. Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.
