In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_rbtree: skip sync GC for new elements in this transaction
New elements in this transaction might expired before such transaction
ends. Skip sync GC for such elements otherwise commit path might walk
over an already released object. Once transaction is finished, async GC
will collect such expired element.
