RDMA\/siw: Bound fragmented header copies by the remaining length<\/p>\n
siw_get_hdr() can receive an extended DDP\/RDMAP header across more than
\none TCP callback. The first callback may receive most of the header,
\nwhile the next one still limits the copy to hdrlen – MIN_DDP_HDR instead
\nof the number of missing bytes. This makes the destination move past the
\nend of the header and overwrite the receive state, including
\nfpdu_part_rcvd. A later callback can then use a negative fpdu_part_rcvd
\nvalue as a copy offset, which creates an OOB write.<\/p>\n
Use the number of header bytes already received when calculating the
\nnext copy length.<\/p>\n","protected":false},"excerpt":{"rendered":"
