Title
netfilter: nft_set_rbtree: skip sync GC for new elements in this transaction
Summary
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.
