To avoid any data races, the socket lock needs to be\nheld with bh_lock_sock().\n\nIf the socket is in use, retry again soon after, similar to what is done\nwith the keepalive timer.","modified":"2026-06-26T11:56:56.300425831Z","published":"2026-05-28T09:35:53.628Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46137.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/013dcdc1961543b9a3433466bc8c79a2f4ca75b5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/23079e0b7742ec114d3507c3e3aad01b7b69e4af"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ad56e434199ca24a812bb353667aa1c3860f513"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5cd6e0ad79d2615264f63929f8b457ad97ae550d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6e4710d7d8782cb61af29a7e7111ddfc38b9e1a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b35605e1f1e877038c8c9d499babbc891cdd234f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc3c0399361efaaf7ae64262eb3f70829b1189c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9b272a85fe6b8f993e37915311e4038c814a533"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46137.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46137"},{"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":"00cfd77b9063dcdf3628a7087faba60de85a9cc8"},{"fixed":"d9b272a85fe6b8f993e37915311e4038c814a533"},{"fixed":"23079e0b7742ec114d3507c3e3aad01b7b69e4af"},{"fixed":"b35605e1f1e877038c8c9d499babbc891cdd234f"},{"fixed":"013dcdc1961543b9a3433466bc8c79a2f4ca75b5"},{"fixed":"6e4710d7d8782cb61af29a7e7111ddfc38b9e1a3"},{"fixed":"2ad56e434199ca24a812bb353667aa1c3860f513"},{"fixed":"cc3c0399361efaaf7ae64262eb3f70829b1189c6"},{"fixed":"5cd6e0ad79d2615264f63929f8b457ad97ae550d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46137.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.259"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46137.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
