linux / linux_kernel
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
