description |
When net_prio and net_cls cgroups are used, cgroup refcount is bogus, as it's not incremented anymore, but decremented when sockets are closed.
This might lead to crashes possibly because of use-after-free when packets are received as shown in LP #1886668.
Cascardo. |
[Impact]
When net_prio and net_cls cgroups are used, cgroup refcount is bogus, as it's not incremented anymore, but decremented when sockets are closed.
This might lead to crashes possibly because of use-after-free when packets are received as shown in LP #1886668.
[Test case]
Ran reproducer from comment #2.
[Regression potential]
We could break the use of cgroup bpf. The use of cgroup bpf looks to still be working from the reproducer. |
