Description

In the Linux kernel, the following vulnerability has been resolved:  netfilter: ipset: drop logically empty buckets in mtype_del  mtype_del() counts empty slots below n->pos in k, but it only drops the bucket when both n->pos and k are zero. This misses buckets whose live entries have all been removed while n->pos still points past deleted slots.  Treat a bucket as empty when all positions below n->pos are unused and release it directly instead of shrinking it further.
