{"id":"CVE-2026-80714","aliases":[],"url":"https://o3.security/vulnerability/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->flags.\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.","published":"2026-08-28T06:53:13.069Z","modified":"2026-08-30T03:48:21.438235649Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.265"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-30T03:48:21.438235649Z"}}
