CVE-2012-2136

Linux Kernel < 3.0.37 - Denial of Service via TUN/TAP Device

Title source: llm

Description

The sock_alloc_send_pskb function in net/core/sock.c in the Linux kernel before 3.4.5 does not properly validate a certain length value, which allows local users to cause a denial of service (heap-based buffer overflow and system crash) or possibly gain privileges by leveraging access to a TUN/TAP device.
