Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: veth: manage XDP program pointers
during channel resize veth_set_channels() tears down XDP resources for removed RX queues without clearing
rq->xdp_prog. If the program is then detached or replaced, those queues keep the old pointer after
