On the\nerror (out:) path the function frees uctx with kfree() but never removes\nit from the list. This leaves a freed node in fcport->unsol_ctx_head: the\nnext list_add_tail() for that fcport writes through the freed node, and a\nsubsequent list_del() can corrupt the list or panic.\n\nUnlink uctx with list_del() before kfree() on the error path, matching the\nother free sites in qla_nvme_release_lsrsp_cmd_kref() and\nqla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only\nreturns the SRB to its pool and does not invoke sp->put_fn, so the out:\npath is the sole free and uctx is always still linked there.","state":0,"publishedAt":"2026-09-25T10:21:30.13+00:00","modifiedAt":"2026-10-21T12:53:03.891+00:00","affected":[{"ecosystem":"Vendor
