The task "linux (Ubuntu)" has expired because it has had no new comments
or updates for more than three years.

If this issue is still present in an Ubuntu LTS kernel still under
active support, please reopen the bug and provide updated details. If
this issue was reported against an Ubuntu kernel no longer under active
support but the issue still exists in a currently supported Ubuntu
kernel, please open a new bug against that kernel version and provide
the updated details, with a reference link to the original bug.

Title:
  openvswitch: nf_ct_put is called with null pointer

Status in linux package in Ubuntu:
  Expired
Status in openvswitch package in Ubuntu:
  Invalid
Status in linux source package in Jammy:
  Fix Committed

Bug description:
  Using an openvswitch bridge with conntrack flows causes a kernel
  warning trace for every packet. This does not break conntrack
  functionality, but causes a big packet forwarding performance
  degradation and very noisy and large kernel.log/journal/syslog/etc.
  The cause is a regression in the 5.15 LTS kernel. This seems to have
  been fixed in mainline 5.15.36, but I don't see the fix in any of the
  jammy branches.

  Upgrading to mainline 5.15.36 or beyond from the Ubuntu PPA fixes the
  problem.

  Here is a relevant discussion with reference to the fix applied to mainline:
