In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Bound fragmented header copies by the remaining length
siw_get_hdr() can receive an extended DDP/RDMAP header across more than
one TCP callback. The first callback may receive most of the header,
while the next one still limits the copy to hdrlen - MIN_DDP_HDR instead
of the number of missing bytes. This makes the destination move past the
end of the header and overwrite the receive state, including
fpdu_part_rcvd. A later callback can then use a negative fpdu_part_rcvd
value as a copy offset, which creates an OOB write.
Use the number of header bytes already received when calculating the
next copy length.
