AI-suggested
A fix is available that addresses the memory overread by validating the number of bytes read from the EC firmware and aborting the operation if the read length does not match expectations. Users should update to patched versions of the Linux kernel that resolve this issue. Specific patched versions are not listed in the provided data, so users should consult their Linux distribution's security advisories for updates corresponding to the affected versions.
Description
A memory overread vulnerability in the Linux kernel's platform/chrome sensorhub component has been resolved. The flaw occurs because the max_response and sensor_num values are read from different EC commands, which can cause a mismatch in expected buffer sizes. This mismatch can lead to an overread during a memcpy operation in the sensorhub ring handler. The vulnerability affects specific Linux kernel versions and has a CVSS score of 7.7, indicating a medium severity level.
