CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 6.1.148/6.6.102/6.12.43/6.16.3. Affected is the function bno055_get_regmask of the file bno055.c of the component iio. The manipulation of the argument hw_xlate_len with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2025-39719 since 04/16/2025. Technical details are known, but there is no available exploit.
