CVE-2025-39719

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: imu: bno055: fix OOB access of hw_xlate array<br /> <br /> Fix a potential out-of-bounds array access of the hw_xlate array in<br /> bno055.c.<br /> <br /> In bno055_get_regmask(), hw_xlate was iterated over the length of the<br /> vals array instead of the length of the hw_xlate array. In the case of<br /> bno055_gyr_scale, the vals array is larger than the hw_xlate array,<br /> so this could result in an out-of-bounds access. In practice, this<br /> shouldn&amp;#39;t happen though because a match should always be found which<br /> breaks out of the for loop before it iterates beyond the end of the<br /> hw_xlate array.<br /> <br /> By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can be<br /> sure we are iterating over the correct length.
