CVE-2026-45873

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