  "description": "In the Linux kernel, the following vulnerability has been resolved:  soc: fsl: qbman: fix race condition in qman_destroy_fq  When QMAN_FQ_FLAG_DYNAMIC_FQID is set, there\u0027s a race condition between fq_table[fq-\u003Eidx] state and freeing/allocating from the pool and WARN_ON(fq_table[fq-\u003Eidx]) in qman_create_fq() gets triggered.  Indeed, we can have:          Thread A                             Thread B     qman_destroy_fq()                    qman_create_fq()       qman_release_fqid()         qman_shutdown_fq()         gen_pool_free()            -- At this point, the fqid is available again --                                            qman_alloc_fqid()            -- so, we can get the just-freed fqid in thread B --                                            fq-\u003Efqid = fqid;                                            fq-\u003Eidx = fqid * 2;                                            WARN_ON(fq_table[fq-\u003Eidx]);                                            fq_table[fq-\u003Eidx] = fq;      fq_table[fq-\u003Eidx] = NULL;  And adding some logs between qman_release_fqid() and fq_table[fq-\u003Eidx] = NULL makes the WARN_ON() trigger a lot more.  To prevent that, ensure that fq_table[fq-\u003Eidx] is set to NULL before gen_pool_free() is called by using smp_wmb().",
