AI-suggested
A patch is available and should be applied to affected Linux kernel versions to prevent the information leak and restore correct sensor functionality. Refer to the vendor advisory (Ubuntu Security Notice USN-8593-1) for the official fix and update instructions.
Description
A vulnerability in the Linux kernel's iio gyro itg3200 driver caused an i2c read operation to write data into the wrong stack location, leading to uninitialized stack data being leaked to userspace and a failure to deliver correct sensor data. This affects certain Linux kernel versions prior to 7.0.0-28.28~24.04.1 and related versions. A patch is available to fix this issue and prevent the information leak while restoring proper sensor functionality.
