CVE-2025-39719

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.
