Descriptions

The sctp_v6_create_accept_sk function in net/sctp/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 sctp_v6_create_accept_sk en net/sctp/ipv6.c en el kernel de Linux hasta la versión 4.11.1 gestiona de manera incorrecta la herencia, lo que permite que usuarios locales provoquen una denegación de servicio (DoS) o, probablemente, causen otro impacto no especificado mediante llamadas de sistema manipuladas. Este problema está relacionado con CVE-2017-8890.

The sctp_v6_create_accept_sk function in net/sctp/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.
