Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: imu: bno055: fix OOB access of hw_xlate array
Fix a potential out-of-bounds array access of the hw_xlate array in
bno055.c.
In bno055_get_regmask(), hw_xlate was iterated over the length of the
vals array instead of the length of the hw_xlate array. In the case of
bno055_gyr_scale, the vals array is larger than the hw_xlate array,
so this could result in an out-of-bounds access. In practice, this
shouldn't happen though because a match should always be found which
breaks out of the for loop before it iterates beyond the end of the
hw_xlate array.
By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can be
sure we are iterating over the correct length.
