  "details": "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-\u003epos in k, but it only drops the bucket when both n-\u003epos and k are zero. This misses buckets whose live entries have all been removed while n-\u003epos still points past deleted slots.  Treat a bucket as empty when all positions below n-\u003epos are unused and release it directly instead of shrinking it further.",
