Description

A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) subsystem, specifically within the rxe component. A local user could trigger a kernel panic by causing an error during the setup of a Queue Pair (QP) in rxe_create_qp(). This occurs when the system attempts to clean up resources by accessing an uninitialized spinlock, leading to a Denial of Service (DoS).
