A user on #ubuntu-server reported being affected by this bug as well but on Focal with the HWE kernel 5.15. I'm not sure how to do verification in such case? Should they manually pull the .deb from jammy-proposed or will there be a HWE kernel built for focal-proposed?

This fixes a regression due to the fix for CVE-2022-3643. [Testing] This has only been build-tested. [Potential regression] Xen guests might not have network access. ---------------------------------------------------------------------- With 5.15.0-58.64-generic, bridge networking on xen is broken : no packet (check with tcpdump) flowing between dom0 and any domUs attached to a network bridge. downgrading to 5.15.0-57-generic fix the issue. Thus the patch to the netback driver seems the cause. relevant network config : brtctl show : br0 8000.XXXXXXXXXXX no eno1 vif1.0 relevant domU config : kernel = '/usr/lib/grub-xen/grub-i386-xen_pvh.bin' type = 'pvh' vif = [ 'ip=192.168.10.10 ,bridge=br0' ] No message in dmesg, journal, xen logs..
