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

RDMA/srpt: Fix srpt_alloc_rw_ctxs() unwind counters

When srpt_alloc_rw_ctxs() fails partway through a multi-buffer indirect
descriptor, the unwind path destroys RDMA contexts but leaves stale
n_rw_ctx and n_rdma values (and a dangling rw_ctxs pointer). Later
sq_wr_avail accounting in srpt_queue_response() or srpt_write_pending()
can then subtract the wrong number of send queue credits.

Reset the counters and clear rw_ctxs after freeing the heap
allocation before returning an error.
