Similar to the connection usage count\nlogic, the waiter signaled by complete() (e.g., in the session release\npath) may wake up and free the iscsit_session structure immediately.\n\nThis creates a race condition where the current thread may attempt to\nexecute spin_unlock_bh() on a session structure that has already been\ndeallocated, resulting in a KASAN slab-use-after-free.\n\nTo resolve this, release the session_usage_lock before calling complete()\nto ensure all dereferences of the sess pointer are finished before the\nwaiter is allowed to proceed with deallocation.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-23193","url":"https://www.suse.com/security/cve/CVE-2026-23193"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"}],"title":"SUSE CVE CVE-2026-23193","tracking":{"current_release_date":"2026-02-16T00:25:14Z","generator":{"date":"2026-02-16T00:25:14Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-23193","initial_release_date":"2026-02-16T00:25:14Z","revision_history":[{"date":"2026-02-16T00:25:14Z","number":"2","summary":"references added,severity changed from  to not set"}],"status":"interim","version":"2"}}}
