DEBIAN-CVE-2026-98323

In the Linux kernel, the following vulnerability has been resolved:  RDMA/siw: Bound fragmented header copies by the remaining length  siwgethdr() 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 - MINDDPHDR instead of the number of missing bytes. This makes the destination move past the end of the header and overwrite the receive state, including fpdupartrcvd. A later callback can then use a negative fpdupartrcvd value as a copy offset, which creates an OOB write.  Use the number of header bytes already received when calculating the next copy length.
