CVE-2026-100075

RDMA/srpt: Fix srpt_alloc_rw_ctxs() unwind counters

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

RDMA/srpt: Fix srptallocrw_ctxs() unwind counters

When srptallocrw_ctxs() fails partway through a multi-buffer indirect

descriptor, the unwind path destroys RDMA contexts but leaves stale

nrwctx and nrdma values (and a dangling rwctxs pointer). Later

sqwravail accounting in srptqueueresponse() or srptwritepending()

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.
