Description
A flaw was found in the Linux kernel's RDMA (Remote Direct Memory Access) subsystem. When connection path initialization fails in the RDMA Transport (RTRS) driver, error cleanup routines invoke event tracing before the associated object name is set. This issue leads to a null pointer dereference, allowing a user or network peer capable of triggering connection errors to crash the system, resulting in a Denial of Service (DoS).
