{"id":"CVE-2026-80714","summary":"ipvs: do not propagate one-packet flag to synced conns","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: do not propagate one-packet flag to synced conns\n\nSynced connections can be created before their destination exists. When\nthe destination is later added, ip_vs_bind_dest() copies connection flags\nfrom the destination into cp-\u003eflags.\n\nIP_VS_CONN_F_ONE_PACKET connections are not synced. If a synced\nconnection inherits IP_VS_CONN_F_ONE_PACKET while it is already hashed,\nexpiry can treat it as a one-packet connection and skip unlinking the\nexisting conn_tab node, leaving stale hash nodes pointing at a freed\nstruct ip_vs_conn.\n\nDrop IP_VS_CONN_F_ONE_PACKET from destination flags when binding synced\nconnections.","modified":"2026-08-31T03:30:55.954021336Z","published":"2026-08-28T06:53:13.069Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80714.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/06d1d9b56ef8132fbf85006885eb43d9510b8b02"},{"type":"WEB","url":"https://git.kernel.org/stable/c/300348e3ba1521b003d59825f97e24f9a6859688"},{"type":"WEB","url":"https://git.kernel.org/stable/c/44af98cc7d5ef8e730488d5df1eecd5deeaa5947"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4649e6faeecdc2d44bfa6ccbe405eef27e55d816"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a63d2dbaeb50a85d4c976b15a36e6b0c7113db5b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/acbdc276091b308ca7794acb86e761f8203e2f59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5ee5b266f833601ac4817f6df0bc496fc376a28"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e7acfc990c29890c883d0d0ce3f737d003a43b44"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80714.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80714"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"26ec037f9841e49cc5c615deb8e1e73e5beab2ca"},{"fixed":"06d1d9b56ef8132fbf85006885eb43d9510b8b02"},{"fixed":"acbdc276091b308ca7794acb86e761f8203e2f59"},{"fixed":"300348e3ba1521b003d59825f97e24f9a6859688"},{"fixed":"44af98cc7d5ef8e730488d5df1eecd5deeaa5947"},{"fixed":"4649e6faeecdc2d44bfa6ccbe405eef27e55d816"},{"fixed":"b5ee5b266f833601ac4817f6df0bc496fc376a28"},{"fixed":"e7acfc990c29890c883d0d0ce3f737d003a43b44"},{"fixed":"a63d2dbaeb50a85d4c976b15a36e6b0c7113db5b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80714.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.36"},{"fixed":"5.10.265"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.216"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.151"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.103"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.44"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80714.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
