  "details": "In the Linux kernel, the following vulnerability has been resolved:  netfilter: nft_set_rbtree: check for partial overlaps in anonymous sets  Userspace provides an optimized representation in case intervals are adjacent, where the end element is omitted.  The existing partial overlap detection logic skips anonymous set checks on start elements for this reason.  However, it is possible to add intervals that overlap to this anonymous where two start elements with the same, eg. A-B, A-C where C \u003c B.        start     end \tA        B       start  end         A     C  Restore the check on overlapping start elements to report an overlap.",
