CVE-2026-74345

RDMA/siw: Fix endpoint/socket association handling

In the Linux kernel, the following vulnerability has been resolved:

RDMA/siw: Fix endpoint/socket association handling

Disassociating a socket from an endpoint via siwsocketdisassoc() may

release the last reference on that endpoint and free it. Therefore, don't

clear the endpoints socket pointer after calling that function, but

within.

This fixes a:

  BUG: KASAN: slab-use-after-free in siwcmworkhandler (drivers/infiniband/sw/siw/siwcm.c:1053 drivers/infiniband/sw/siw/siw_cm.c:1075)

which occurred after processing a malformed MPA request during connection

establishment, causing the new endpoint to be closed.
