Hi stable maintainers,

I'd like to ask you to include the following patch to stable:

080f22f5d30233faf3d83be3098f35b8be9b7a00 
("vsock/virtio: fix MSG_PEEK ignoring skb offset when calculating bytes to copy")

This fixes a bug in virtio-vsock, that leads to an EFAULT when the user
performs a partial recv followed by a peek that requests more bytes than
are available.

Please apply it to
- 6.12.y
- 6.18.y

7.0.y already has it.

Luigi
