Dear kernel developers,
I found that on the syzbot dashboard, “KASAN: null-ptr-deref Write in
event_handler”[1] and
"KASAN: null-ptr-deref Write in vhci_shutdown_connection" () should
share the same root cause.
The reasons for the above statement:
1) the stack trace is the same, and this title difference is due to
the inline property of "vhci_shutdown_connection";
2) their PoCs are the same as each other.
If you can have any issues with this statement or our information is
useful to you, please let us know. Thanks very much.
