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...

kernel: RDMA/mlx5: Fix error path fall-through in mlx5_ib_dev_res_srq_init()

A flaw was found in the Linux kernel's RDMA/mlx5 component. An error path fall-through in the mlx5ibdevressrqinit function, specifically when ibcreatesrq fails, can lead to the use of freed memory and error pointers. This memory corruption vulnerability could result in system instability, denial ...
