The\ncaller qla2x00_status_entry() acknowledges this on the very same status\npath, re-fetching GET_CMD_SP(sp) and bailing out with the \"Command\nalready returned\" message when it is NULL -- but that check runs only\nafter qla_chk_edif_rx_sa_delete_pending() has already dereferenced the\npointer, so a NULL cmd crashes the kernel in interrupt context.\n\nReturn early when cmd is NULL, before touching cmd->sc_data_direction.","published":"2026-09-16T11:16:54.353","modified":"2026-09-16T11:16:54.353","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2191b0034a2f1307d421782e6eceddf8eec9e7f6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/75fd6d041c4a325ae37f4683e6678d3015988bb0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94bfb61478bcb207d27f8cd24fd231421059519f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96eb8a3fc9f7fe7ba32679fcf1d2fd7d251e7a8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c20ee380ca59c5a8646750c4849969a815924e2e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de0c8ef3b900c5e971c82ef38c6f5c22c5f3d8c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e479e9b148456905d12711411484b94083c8ff58"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T11:16:54.353"}}
