CVE-2022-49183
In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: fix ref leak when switching zones When switching zones or network namespaces without doing a ct clear in between, it is now leaking a reference to the old ct entry. That's because tcfctskbnfctcached returns fals...
