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.","published":"2026-08-15T05:58:33.906Z","modified":"2026-08-18T03:56:56.948664161Z","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":"6.12.97"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:56.948664161Z"}}
