Description OSIDB Bzimport 2024-09-27 13:22:34 UTC 
In the Linux kernel, the following vulnerability has been resolved:

um: line: always fill *error_out in setup_one_line()

The pointer isn't initialized by callers, but I have
encountered cases where it's still printed; initialize
it in all possible cases in setup_one_line().
