Summary
In the Linux kernel, the following vulnerability has been resolved: sched: act_ct: take care of padding in struct zones_ht_key Blamed commit increased lookup key size from 2 bytes to 16 bytes, because zones_ht_key got a struct net pointer. Make sure rhashtable_lookup() is not using the padding bytes which are not initialized.
