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.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.63%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
