Hi,
Upstream commit id: 397430b50a363d8b7bdda00522123f82df6adc5e
should be applied because it fixes an Oops (divide by zero) that can be
triggered from user space. See:
https://syzkaller.appspot.com/bug?id=2ebf7e5eb303ac9a598e0dab2c0c8b03ead7abce
It should be applied to stable kernels: 5.14, 5.10, 5.4, 4.19, 4.14, 4.9, 4.4

Thanks,
Tadeusz

It's already in the latest stable -rc releases, do you not see it there?

I haven't checked the rc releases, just the latest stable versions.
Now I also see Sasha Levin's submissions on the stable mailing list archive.
All good. Sorry for the noise.

Also note that there is a bug in this commit, so it was dropped from the
stable queues until the fix for this hits Linus's tree.

Good to know. Ideally we could also add some netif_warn() message for the user.

Why? It's an "obviously broken" device that is created just to try to
harm the kernel. No need to be noisy about it.
