{"id":"CVE-2026-90154","summary":"ksmbd: scope session state changes to bound connections","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: scope session state changes to bound connections\n\nksmbd_all_conn_set_status() treats every connection whose transient\nbinding flag is set as belonging to the target SessionId.  A logoff or\nsession replacement can consequently move an unrelated connection to\nNEED_RECONNECT or NEED_SETUP.\n\nPass the target session itself and select connections using either the\nconnection-local session xarray or the session's permanent channel list.\nUse the same association test while waiting for requests to drain.\n\nSerialize session-wide status changes under request_lock and do not\noverwrite EXITING or RELEASING. Protect the shutdown transition with the\nsame lock so a concurrent session update cannot revive a closing\nconnection.","modified":"2026-09-19T03:47:24.920098927Z","published":"2026-09-17T16:06:47.046Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90154.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0875872718b98e8530fbc634e5aa7dbd3253b80d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c50e628122aed077695669e25b842e778511a43d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90154.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90154"},{"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":"f5a544e3bab78142207e0242d22442db85ba1eff"},{"fixed":"0875872718b98e8530fbc634e5aa7dbd3253b80d"},{"fixed":"c50e628122aed077695669e25b842e778511a43d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90154.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90154.json"}}],"schema_version":"1.9.0"}
