Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
iio: imu: kmx61: fix information leak in triggered buffer
The ‘buffer’ local array is used to push data to user space from a triggered buffer, but it does not set values for inactive channels, as it only uses iio_for_each_active_channel() to assign new values.
Initialize the array to zero before using it to avoid pushing uninitialized information to userspace.
