AV:L/AC:L/Au:N/C:C/I:C/A:C

The kernel-rt package is vulnerable to denial of service(DoS). The attack exists because of a use-after-free flaw in the way the Linux kernel’s Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. allowing a local privileged user to trigger the attack.
