kernel: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()
A flaw was found in the Linux kernel's RDMA/mlx4 component. This vulnerability arises from the incorrect use of Read-Copy Update RCU in the mlx4srqevent function. An attacker could potentially trigger an event before the srq object is fully initialized, leading to a system crash. This could resul...
