Ubuntu.comUB:CVE-2021-47514CVE-2021-47514
In the Linux kernel, the following vulnerability has been resolved:
devlink: fix netns refcount leak in devlink_nl_cmd_reload() While preparing
my patch series adding netns refcount tracking, I spotted bugs in
devlink_nl_cmd_reload() Some error paths forgot to release a refcount on a
netns. To fix this, we can reduce the scope of get_net()/put_net() section
around the call to devlink_reload().
