In commit 357d23c811a7 ("Remove the obsolete libibcm library")
in rdma-core [1], we removed obsolete library which used the
/dev/infiniband/ucmX interface.
Following multiple syzkaller reports about non-sanitized
user input in the UCMA module, the short audit reveals the same
issues in UCM module too.
It is better to disable this interface in the kernel,
before syzkaller team invests time and energy to harden
this unused interface.

Userspace InfiniBand access support. This enables the

kernel side of userspace verbs and the userspace
|
|
communication manager (CM). This allows userspace processes
|
|
to set up connections and directly access InfiniBand

hardware for fast-path operations. You will also need

libibverbs, libibcm and a hardware driver library from

The UCM module has known security flaws, which no one is
|
|
interested to fix. The user-space part of this code was
|
|
dropped from the upstream a long time ago.

This option is DEPRECATED and planned to be removed.
