CVE-2021-47078

Concrete details available: CVE-2021-47078 affects the Linux kernel’s RDMA/rxe driver. The flaw occurs in rxe_qp_do_cleanup() when rxe_qp_from_init() has failed, causing QP fields to be garbage-collected and leading to a refcount underflow and a use-after-free condition. This can enable local exp...
