{"id":"CVE-2024-46711","summary":"mptcp: pm: fix ID 0 endp usage after multiple re-creations","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmptcp: pm: fix ID 0 endp usage after multiple re-creations\n\n'local_addr_used' and 'add_addr_accepted' are decremented for addresses\nnot related to the initial subflow (ID0), because the source and\ndestination addresses of the initial subflows are known from the\nbeginning: they don't count as \"additional local address being used\" or\n\"ADD_ADDR being accepted\".\n\nIt is then required not to increment them when the entrypoint used by\nthe initial subflow is removed and re-added during a connection. Without\nthis modification, this entrypoint cannot be removed and re-added more\nthan once.","modified":"2026-04-02T12:19:30.121788Z","published":"2024-09-13T06:33:42.956Z","related":["SUSE-SU-2024:3553-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/46xxx/CVE-2024-46711.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/119806ae4e46cf239db8e6ad92bc2fd3daae86dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/53e2173172d26c0617b29dd83618b71664bed1fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9366922adc6a71378ca01f898c41be295309f044"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c9c744666f7308a4daba520191e29d395260bcfe"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/46xxx/CVE-2024-46711.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-46711"},{"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":"3ad14f54bd7448384458e69f0183843f683ecce8"},{"fixed":"c9c744666f7308a4daba520191e29d395260bcfe"},{"fixed":"53e2173172d26c0617b29dd83618b71664bed1fb"},{"fixed":"119806ae4e46cf239db8e6ad92bc2fd3daae86dc"},{"fixed":"9366922adc6a71378ca01f898c41be295309f044"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-46711.json"}}],"schema_version":"1.7.5"}
