{"id":"CVE-2021-47203","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: lpfc: Fix list_add() corruption in lpfc_drain_txq()\n\nWhen parsing the txq list in lpfc_drain_txq(), the driver attempts to pass\nthe requests to the adapter. If such an attempt fails, a local \"fail_msg\"\nstring is set and a log message output.  The job is then added to a\ncompletions list for cancellation.\n\nProcessing of any further jobs from the txq list continues, but since\n\"fail_msg\" remains set, jobs are added to the completions list regardless\nof whether a wqe was passed to the adapter.  If successfully added to\ntxcmplq, jobs are added to both lists resulting in list corruption.\n\nFix by clearing the fail_msg string after adding a job to the completions\nlist. This stops the subsequent jobs from being added to the completions\nlist unless they had an appropriate failure.","modified":"2026-03-13T05:18:04.602374Z","published":"2024-04-10T19:15:48.217Z","related":["SUSE-SU-2024:1641-1","SUSE-SU-2024:1642-1","SUSE-SU-2024:1643-1","SUSE-SU-2024:1644-1","SUSE-SU-2024:1645-1","SUSE-SU-2024:1646-1","SUSE-SU-2024:1647-1","SUSE-SU-2024:1650-1","SUSE-SU-2024:1659-1","SUSE-SU-2024:1663-1","SUSE-SU-2024:1870-1"],"references":[{"type":"FIX","url":"https://git.kernel.org/stable/c/814d3610c4ce86e8cf285b2cdac0057a42e82de5"},{"type":"FIX","url":"https://git.kernel.org/stable/c/99154581b05c8fb22607afb7c3d66c1bace6aa5d"},{"type":"FIX","url":"https://git.kernel.org/stable/c/ad4776b5eb2e58af1226847fcd3b4f6d051674dd"},{"type":"FIX","url":"https://git.kernel.org/stable/c/b291d147d0268e93ad866f8bc820ea14497abc9b"},{"type":"FIX","url":"https://git.kernel.org/stable/c/c097bd5a59162156d9c2077a2f58732ffbaa9fca"},{"type":"FIX","url":"https://git.kernel.org/stable/c/ec70d80a8642900086447ba0cdc79e3f44d42e8f"},{"type":"FIX","url":"https://git.kernel.org/stable/c/f05a0191b90156e539cccc189b9d87ca2a4d9305"},{"type":"FIX","url":"https://git.kernel.org/stable/c/16bcbfb56d759c25665f786e33ec633b9508a08f"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-47203.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"4.4.293"}]},{"events":[{"introduced":"4.5"},{"fixed":"4.9.291"}]},{"events":[{"introduced":"4.10"},{"fixed":"4.14.256"}]},{"events":[{"introduced":"4.15"},{"fixed":"4.19.218"}]},{"events":[{"introduced":"4.20"},{"fixed":"5.4.162"}]},{"events":[{"introduced":"5.5"},{"fixed":"5.10.82"}]},{"events":[{"introduced":"5.11"},{"fixed":"5.15.5"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
