Description
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.
