Descriptions
In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Fix connection failure handling
In case immediate MPA request processing fails, the newly
created endpoint unlinks the listening endpoint and is
ready to be dropped. This special case was not handled
correctly by the code handling the later TCP socket close,
causing a NULL dereference crash in siw_cm_work_handler()
when dereferencing a NULL listener. We now also cancel
the useless MPA timeout, if immediate MPA request
processing fails.
This patch furthermore simplifies MPA processing in general:
Scheduling a useless TCP socket read in sk_data_ready() upcall
is now surpressed, if the socket is already moved out of
TCP_ESTABLISHED state.
A NULL dereference vulnerability was found in the Linux kernel, which is caused when the siw_cm_work_handler() function attempts to dereference a NULL listener that may be created when immediate MPA request processing fails and the newly created endpoint unlinks the listening endpoint ready to be dropped.
