Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：smb: smbdirect: destroy QP before mem pools on accept failure On the rdma_accept_failed error path of smbdirect_accept_connect_request(), the receive io posted just above is owned by the QP (recv_io is set to NULL after a successful post). The error path fell through to smbdirect_connection_destroy_mem_pools() before smbdirect_connection_destroy_qp(), so the mem pools and the recv_io slab cache were destroyed while that recv_io was still outstanding on the QP. The drain in smbdirect_connection_destroy_qp() (ib_drain_qp()) is what runs the recv completion that returns the recv_io to the free list, so destroying the pools first leaves the object outstanding at kmem_cache_destroy() time (Slab cache still has objects) and later frees it into an already-destroyed mempool (mempool_free_bulk NULL-pointer dereference). Give rdma_accept_failed its own teardown that drains the QP first, then destroys the mem pools, and returns.
    The remaining labels (post_recv_io_failed onward) run before the recv_io was ever posted, so they keep the mem-pools-then-qp order. The outstanding recv_io at kmem_cache_destroy() time: [ 3487.344647] ============================================================================= [ 3487.349942] BUG smbdirect_recv_io_cache_ffff88811ba99000 (Not tainted): Objects remaining on __kmem_cache_shutdown() [3487.356078] ----------------------------------------------------------------------------- [ 3487.356078] [ 3487.356738] Object 0xffff8881511c3440 @offset=13376 [ 3487.358464] Allocated in mempool_alloc_noprof+0x18c/0x290 age=1194 cpu=6 pid=22254 [ 3487.361197] mempool_alloc_noprof+0x18c/0x290 [ 3487.361542] smbdirect_connection_create_mem_pools+0x405/0x780 [ 3487.361972] smbdirect_accept_connect_request+0x5a8/0x1b80 [ 3487.362359] smbdirect_listen_rdma_event_handler+0x1579/0x1b90 [ 3487.362779] cma_cm_event_handler+0x9c/0x230 [3487.363096] cma_ib_req_handler+0x2682/0x45d0 [ 3487.363414] cm_process_work+0x56/0x3d0 [ 3487.363676] cm_work_handler+0x8a0e/0xd000 [ 3487.367496] process_scheduled_works+0xa07/0x13a0 [ 3487.367859] worker_thread+0x7c9/0xc80 [ 3487.368148] kthread+0x341/0x430 [ 3487.368407] ret_from_fork+0x3a8/0x7a0 [3487.368704] ret_from_fork_asm+0x1a/0x30 [ 3487.370307] Slab 0xffffea0005447000 objects=19 used=1 fp=0xffff8881511c0040 flags=0x100000000000240(workingset|head|node=0|zone=2) [ 3487.372840] ------------[cut here ]------------ [ 3487.373195] WARNING: mm/slub.c:1244 at __slab_err+0x1a/0x30, CPU#6:
