CVE-2021-47078

CVE-2021-47078 affects the Linux kernel RDMA/rxe path. The root cause is in rxe_qp_from_init() where, if QP initialization fails, the code could leave QP fields garbage. This leads to a use-after-free scenario with a refcount underflow in refcount.c (totally described in the given stack trace), c...
