Use of uninitialized value in hex at /usr/share/perl5/vendor_perl/NeedRestart/uCode/AMD.pm line 175.

[ndias]

I have the error
Use of uninitialized value in hex at /usr/share/perl5/vendor_perl/NeedRestart/uCode/AMD.pm line 175.

when running needrestart, I'm using the version 3.8

This is the result of running needrestart -v -w

$ needrestart -v -w
