The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel through 4.14.11 allows attackers to cause a denial of service (slab out-of-bounds write) or possibly have unspecified other impact via vectors involving TLS.

CVE-2018-5703 [CRITICAL] CWE-787 kernel: net/ipv6/tcp_ipv6.c: tcp_v6_syn_recv_sock function allows attackers to cause a denial of service
kernel: net/ipv6/tcp_ipv6.c: tcp_v6_syn_recv_sock function allows attackers to cause a denial of service
The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel through 4.14.11 allows attackers to cause a denial of service (slab out-of-bounds write) or possibly have unspecified other impact via vectors involving TLS.
The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel, through 4.14.11, allows attackers to cause a denial of service (slab out-of-bounds write) or possibly have unspecified other impact via vectors involving in-kernel TLS implementation. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
