      "title": "vxlan: mdb: Fix source list corruption on a failed replace",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nvxlan: mdb: Fix source list corruption on a failed replace\n\nWhen replacing the source list of an MDB remote entry, all existing\nsources are first marked for deletion and vxlan_mdb_remote_srcs_add()\nis then called to add the new source list. Sources present in the new\nlist have their deletion mark cleared, and any sources left marked\nafterwards are removed.\n\nIf vxlan_mdb_remote_srcs_add() fails partway through, its error path\ndeletes all entries on the remote's source list. That rollback is only\ncorrect for its other caller, vxlan_mdb_remote_add(), where the remote\nwas just allocated and the list contains solely entries added during\nthe call. On the replace path the list also holds pre-existing sources,\nso a failed replace tears them down together with their (S, G)\nforwarding entries instead of leaving the entry unchanged.\n\nThis is reachable from an existing (*, G) remote. An EXCLUDE filter\nthat loses sources starts forwarding traffic that should be blocked,\nwhile an INCLUDE filter that loses sources drops traffic that should be\nforwarded.\n\nMark entries created during the current pass with a new\nVXLAN_SGRP_F_NEW flag. On failure, delete only those entries and clear\nthe deletion mark on the pre-existing ones, so a failed replace leaves\nthe source list untouched. Retain the flag until the whole operation\nsucceeds and then clear it. Also stop vxlan_mdb_remote_src_add() from\ndeleting a pre-existing entry it only looked up when adding that\nentry's forwarding entry fails.",
