The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the compare_netdev_and_ip() function in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. A local user can trigger an out-of-bounds read error and read contents of memory on the system.
