Hi Slava,
Thank you for taking your time.

We originally obtained this issue's syz and C reproducers using Syzkaller's repro tool (refer to the URL below). The issue was triggered when we ran the syz reproducer through Syzkaller.

Url: https://github.com/google/syzkaller/blob/master/docs/reproducing_crashes.md

Syzkaller also provides syz-execprog to verify whether the C program can trigger the issue. We are currently in the process of verifying whether the C reproducer can reliably reproduce the issue. Please allow us some time to complete this verification.

We'll follow up with you once we have more concrete results.

Best regards,
Kun
