Description OSIDB Bzimport 2026-08-10 12:01:28 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: core: fix uninitialized data in debugfs

If *ppos is non-zero then simple_write_to_buffer() will not initialize
the start of buf[].  Non zero values for *ppos aren't going to work
anyway.  Test for them at the start of the function and return -EINVAL.
