Hello,
The 6.6.y branch has the patch already in the stable queue -> https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/comm..., and it should be available in the 6.6.46 upcoming minor.
Thanks, Adrian.
Yeah it's also queued up for 6.10, which I both missed (sorry for that!). If I'm able to properly backport the patch for 6.1 I'll send that one, but my hopes are not too high that this will work ..
There are two conflicts.
The one in include/linux/virtio_net.h is resolved by first backporting commit fc8b2a6194693 ("net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation")
We did not backport that to stable because there was some slight risk that applications might be affected. This has not surfaced.
The conflict in net/ipv4/udp_offload.c is not so easy to address. There were lots of patches between v6.1 and linus/master, with far fewer of these betwee v6.1 and linux-stable/linux-6.1.y.
BTW, we successfully cherry-picked 3 suggested[1] commits over v6.1.105 in ALT, and there is no reported problems as of yet.

That's good to hear.
These are all fine to go to 6.1 stable.
