The kernel fix for this, in conntrack, is in the 5.17 series:

https://lore.kernel.org/netdev/17c87824-7d04-c34e-bf6a-d8b874242636@tmb.nu/t/#mab1f2792ba24e98e3f41468c9781747a77c87ac9

Closing as not-a-bug (for Exim).
The above workaround patch should be pulled out again once
enough time has passed for the major distros to be either using a kernel
that new, or have backported the patch.

Hello,

I had a hard time parsing, but now I get it. Once the linux bugfix has been
applied to the major linux distributions the exim workaround can be reverted
("pulled out").

Thanks.
