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.","state":0,"publishedAt":"2026-08-10T11:58:34.612+00:00","modifiedAt":"2026-10-19T20:58:51.286+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/vxlan/vxlan_mdb.c\"\n ],\n \"versions\": [\n {\n \"version\": \"a3a48de5eade770e911d35291217bdd69ce04ef1\",\n \"lessThan\": \"5bc8fc1d2ff802eec839e03adef5df597421898d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"a3a48de5eade770e911d35291217bdd69ce04ef1\",\n \"lessThan\": \"2c54dff57606590fa4abec46bab6bea3133f1539\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"a3a48de5eade770e911d35291217bdd69ce04ef1\",\n \"lessThan\": \"79370b573e92e8f190eb5f9a511fa5398340d8b2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"a3a48de5eade770e911d35291217bdd69ce04ef1\",\n \"lessThan\": \"54a3c27b357dfb34f327f89bfadeb998bef8051e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"a3a48de5eade770e911d35291217bdd69ce04ef1\",\n \"lessThan\": \"dcd9b465965422b9654f6026e8a2fa8984f74c3c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/vxlan/vxlan_mdb.c\"\n ],\n \"versions\": [\n {\n \"version\": \"6.4\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"6.4\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.148\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.101\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.42\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.6\",\n \"lessThanOrEqual\": \"7.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:H","score":7.9,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/5bc8fc1d2ff802eec839e03adef5df597421898d","https://git.kernel.org/stable/c/2c54dff57606590fa4abec46bab6bea3133f1539","https://git.kernel.org/stable/c/79370b573e92e8f190eb5f9a511fa5398340d8b2","https://git.kernel.org/stable/c/54a3c27b357dfb34f327f89bfadeb998bef8051e","https://git.kernel.org/stable/c/dcd9b465965422b9654f6026e8a2fa8984f74c3c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-68116","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-68116","identifiers":["CVE-2026-68116"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
