Description OSIDB Bzimport 2025-01-19 12:02:57 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: light: bh1745: fix information leak in triggered buffer

The 'scan' local struct 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 struct to zero before using it to avoid pushing
uninitialized information to userspace.
