Description OSIDB Bzimport 2025-06-18 12:10:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()

The simple_write_to_buffer() function will succeed if even a single
byte is initialized.  However, we need to initialize the whole buffer
to prevent information leaks.  Just use memdup_user().
