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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/2191b0034a2f1307d421782e6eceddf8eec9e7f6","tags":[]},{"url":"https://git.kernel.org/stable/c/75fd6d041c4a325ae37f4683e6678d3015988bb0","tags":[]},{"url":"https://git.kernel.org/stable/c/94bfb61478bcb207d27f8cd24fd231421059519f","tags":[]},{"url":"https://git.kernel.org/stable/c/96eb8a3fc9f7fe7ba32679fcf1d2fd7d251e7a8b","tags":[]},{"url":"https://git.kernel.org/stable/c/c20ee380ca59c5a8646750c4849969a815924e2e","tags":[]},{"url":"https://git.kernel.org/stable/c/de0c8ef3b900c5e971c82ef38c6f5c22c5f3d8c1","tags":[]},{"url":"https://git.kernel.org/stable/c/e479e9b148456905d12711411484b94083c8ff58","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
