Description

In the Linux kernel, the following vulnerability has been resolved:  RDMA/siw: Fix potential NULL pointer dereference in header processing  If siw_get_hdr() returns -EINVAL before set_rx_fpdu_context(), qp->rx_fpdu can be NULL. The error path in siw_tcp_rx_data() dereferences qp->rx_fpdu->more_ddp_segs without checking, which may lead to a NULL pointer deref. Only check more_ddp_segs when rx_fpdu is present.  KASAN splat: [  101.384271] KASAN: null-ptr-deref in range [0x00000000000000c0-0x00000000000000c7] [  101.385869] RIP: 0010:siw_tcp_rx_data+0x13ad/0x1e50
