CVE-2015-2041

net/llc/sysctl_net_llc.c en el kernel de Linux anterior a 3.19 utiliza un tipo de datos incorrecto en una tabla sysctl, lo que permite a usuarios locales obtener información sensible de la memoria del kernel o posiblemente tener otro impacto no especificado mediante el acceso a una entrada sysctl.

It was discovered that the Linux kernel's Infiniband subsystem did not properly sanitize its input parameters while registering memory regions from userspace. A local user could exploit this flaw to cause a denial of service (system crash) or to potentially gain administrative privileges. An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) mitigation mechanism. Various other issues were also addressed.
