NVD

In the Linux kernel, the following vulnerability has been resolved:

net: shaper: reject duplicate leaves in GROUP request

net shaper nl group doit() does not deduplicate NET SHAPER A LEAVES entries. When userspace supplies the same leaf handle twice, the same old-parent pointer lands twice in old nodes[]. The cleanup loop double frees the parent. Of course the same parent may still be in old nodes[] twice if we are moving multiple of its leaves.

Note that this patch also implicitly fixes the fact that the i >= leaves count path forgets to set ret.
