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.
