Linux kernel is vulnerable to denial of service attacks. The rds_cmsg_atomic function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. An attacker with local access can cause denial of service conditions via NULL pointer dereference in rds_atomic_free_op.
