Описание
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.
Отчет
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, and 7, its real-time kernel, Red Hat Enterprise MRG 2, Red Hat Enterprise Linux 7 for ARM 64 and Red Hat Enterprise Linux 7 for Power 9 LE. The code of in-kernel TLS implementation with the flaw is not enabled and is not built in the products listed.
