Description OSIDB Bzimport 2025-01-19 12:02:41 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: adc: ti-ads1119: fix information leak in triggered buffer

The 'scan' local struct is used to push data to user space from a
triggered buffer, but it has a hole between the sample (unsigned int)
and the timestamp. This hole is never initialized.

Initialize the struct to zero before using it to avoid pushing
uninitialized information to userspace.
