Descriptions

The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel through 4.11.1 mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890.

La función tcp_v6_syn_recv_sock en el archivo net/ipv6/tcp_ipv6.c en el kernel de Linux hasta versión 4.11.1, el manejo inapropiado de la herencia, permite a los usuarios locales causar una denegación de servicio o posiblemente tener otro impacto no especificado por medio de llamadas del sistema, un problema relacionado con CVE-2017 -8890.

The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
