The kernel-rt packages is susceptible to denial of service (DoS). The attack is possible because it does not make sure the addr_len value to get initialized with the associated data structure, allowing a local unauthorized user to do the recvmsg, recvfrom, and recvmmsg system calls to leak kernel stack memory to user space.
