Subject: Re: WARNING in do_notify_parent (kernel/signal.c:2174)
Date: Thu, 07 May 2026 17:45:23 +0200 [thread overview]
Message-ID: <f52d0978a5c20e4f9f738881cc1c47a3.y2k@desarrollaria.com> (raw)
Follow-up: I found that commit 0f8e38eeb995 by Oleg Nesterov
("do_notify_parent: sanitize the valid_signal() checks") appears to be
related to this WARNING.
The syzkaller reproducer confirms the WARN_ON_ONCE fires in real
conditions via syz_clone() with specific arguments.
Kernel tested: 7.1.0-rc2-00099-gadc1e5c6203c
Thanks,
