Sorry for the late reply, I don't know the REPORT information of syzbot because I haven't deployed it. The attached reproduction program was generated by syz-repro. As you can see from the repro.cprog, the bug occurred in the case of fault injection.
In repro.cprog, line 108-109: inject_fault(81); syscall(__NR_ioctl, r[0], 0x5423, 0x20000080ul);
