Dear Linux kernel developers,

I found the crash "KASAN: use-after-free Read in vc_do_resize" and "KASAN:
use-after-free Read in screen_glyph_unicode" when running syzkaller, hope
it?s unknown:

Linux version: 1c163f4c7b3f Linux 5.0
Branch: drivers/tty/vt/vt.c

Please get C repo and crash log generated by syzkaller from google
drive https://drive.google.com/drive/folders/1Uns5nkH8oh0LwJfAzJDfBBkVRVhOHOx1?usp=sharing,
as well as the .config I used for linux kernel from the attachment.
Thanks.

Thanks,
Wei
