Linux Kernel rds_cmsg_rdma_args denial of service
|kernel-rdscmsgrdmaargs-dos (64618)||Medium Risk|
Linux Kernel is vulnerable to a denial of service, caused by an integer overflow in the rds_cmsg_rdma_args function. By sending a specially-crafted Reliable Datagram Sockets (RDS) request, a local attacker could exploit this vulnerability to possibly corrupt memory or cause a denial of service.
