Therefore, don't\nclear the endpoints socket pointer after calling that function, but\nwithin.\n\nThis fixes a:\n\n  BUG: KASAN: slab-use-after-free in siw_cm_work_handler (drivers/infiniband/sw/siw/siw_cm.c:1053 drivers/infiniband/sw/siw/siw_cm.c:1075)\n\nwhich occurred after processing a malformed MPA request during connection\nestablishment, causing the new endpoint to be closed.","modified":"2026-09-18T10:11:51.150998367Z","published":"2026-08-15T05:58:33.906Z","related":["SUSE-SU-2026:23477-1","SUSE-SU-2026:23481-1","SUSE-SU-2026:23528-1","SUSE-SU-2026:23529-1","SUSE-SU-2026:4120-1","SUSE-SU-2026:4254-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74345.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b28d513393f81e2de00f82970487a9d001557e4e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6cf763eee0a932792bef64ceaca568d324192fc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ea4f6f6c53577fb3f05dbd78b15e586772d49831"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6183983ce1ff254d629a333739082b39d7c5eb6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74345.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74345"},{"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":"6c52fdc244b5ccc468006fd65a504d4ee33743c7"},{"fixed":"b28d513393f81e2de00f82970487a9d001557e4e"},{"fixed":"f6183983ce1ff254d629a333739082b39d7c5eb6"},{"fixed":"b6cf763eee0a932792bef64ceaca568d324192fc"},{"fixed":"ea4f6f6c53577fb3f05dbd78b15e586772d49831"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-74345.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.3.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-74345.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"}]}
