- Summary
- net: shaper: reject duplicate leaves in GROUP request
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: shaper: reject duplicate leaves in GROUP request
netshapernlgroupdoit() does not deduplicate NETSHAPERALEAVES entries. When userspace supplies the same leaf handle twice, the same old-parent pointer lands twice in oldnodes[]. 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.
