Subject: [Linux Kernel Bug] WARNING in remove_vm_area

Dear Linux kernel developers and maintainers:

We are writing to report a kernel WARNING in remove_vm_area,
discovered with our modified version of syzkaller.

This issue was initially found in kernel v6.17-rc5 (commit
76eeb9b8de9880ca38696b2fb56ac45ac0a25c6c). Unfortunately, we do not
have a stable C or Syz program to reproduce this warning. We are
actively analyzing the root cause and working to create a reliable
reproducer, which we will share as soon as it is available.

Attached are the kernel console output and the .config file for your
analysis. Please let us know if any further information would be
helpful.

Best regards,
Jiaming Zhang
