    RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event

    In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event If siw_recv_mpa_rr returns -EAGAIN, it means that the MPA reply hasn't been received completely, and should not report IW_CM_EVENT_CONNECT_REPLY in this case. This may trigger a call trace in iw_cm. A simple way to trigger this: server: ib_send_lat client: ib_send_lat -R <server_ip> The call trace looks like this: kernel BUG at drivers/infiniband/core/iwcm.c:894! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI <...> Workqueue: iw_cm_wq cm_work_handler [iw_cm] Call Trace: <TASK> cm_work_handler+0x1dd/

    RDMA/hfi1: fix potential memory leak in setup_base_ctxt()

    In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: fix potential memory leak in setup_base_ctxt() setup_base_ctxt() allocates a memory chunk for uctxt->groups with hfi1_alloc_ctxt_rcv_groups(). When init_user_ctxt() fails, uctxt->groups is not released, which will lead to a memory leak. We should release the uctxt->groups with hfi1_free_ctxt_rcv_groups() when init_user_ctxt() fails.

    usb: cdns3: change place of 'priv_ep' assignment in cdns3_gadget_ep_dequeue(), cdns3_gadget_ep_enable()

    In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: change place of 'priv_ep' assignment in cdns3_gadget_ep_dequeue(), cdns3_gadget_ep_enable() If 'ep' is NULL, result of ep_to_cdns3_ep(ep) is invalid pointer and its dereference with priv_ep->cdns3_dev may cause panic. Found by Linux Verification Center (linuxtesting.org) with SVACE.

    HID: mcp2221: prevent a buffer overflow in mcp_smbus_write()

    In the Linux kernel, the following vulnerability has been resolved: HID: mcp2221: prevent a buffer overflow in mcp_smbus_write() Smatch Warning: drivers/hid/hid-mcp2221.c:388 mcp_smbus_write() error: __memcpy() '&mcp->txbuf[5]' too small (59 vs 255) drivers/hid/hid-mcp2221.c:388 mcp_smbus_write() error: __memcpy() 'buf' too small (34 vs 255) The 'len' variable can take a value between 0-255 as it can come from data->block[0] and it is user data. So add an bound check to prevent a buffer overflow in memcpy().

    RDMA/srpt: Fix a use-after-free

    In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Fix a use-after-free Change the LIO port members inside struct srpt_port from regular members into pointers. Allocate the LIO port data structures from inside srpt_make_tport() and free these from inside srpt_make_tport(). Keep struct srpt_device as long as either an RDMA port or a LIO target port is associated with it. This patch decouples the lifetime of struct srpt_port (controlled by the RDMA core) and struct srpt_port_id (controlled by LIO). This patch fixes the following KASAN complaint: BUG: KASAN: use-after-free in srpt_enable_tpg+0x31/0x70 [ib_srpt]

    RDMA/rxe: Fix error unwind in rxe_create_qp()

    In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix error unwind in rxe_create_qp() In the function rxe_create_qp(), rxe_qp_from_init() is called to initialize qp, internally things like the spin locks are not setup until rxe_qp_init_req(). If an error occures before this point then the unwind will call rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task() which will oops when trying to access the uninitialized spinlock. Move the spinlock initializations earlier before any failures.
