Vulnerability from cvelistv5

Severity ?
Summary
An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.

The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.\"},{\"lang\":\"es\",\"value\":\"Se detecto un problema en net / ipv6 / ip6mr.c en el kernel de Linux antes de 4.11. Al establecer una opción de socket específica, un atacante puede controlar un puntero en la tierra del kernel y causar una falla de protección general inet_csk_listen_stop, o potencialmente ejecutar código arbitrario bajo ciertas circunstancias. El problema se puede desencadenar como root (por ejemplo, dentro de un contenedor LXC predeterminado o con la capacidad CAP_NET_ADMIN) o después de compartir el espacio de nombres.
