The kernel packages is vulnerable to use-after-free flaw. Linux kernel’s Datagram Congestion Control Protocol (DCCP) implementation has a flaw in freeing SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket, allowing a local user with little privilege to compromise the kernel memory and escalate their privileges on the system.
