Vulnerability Name:

CVE-2012-2136 (CCN-75964)

Assigned:2012-05-29
Published:2012-05-29
Updated:2023-02-13
Summary: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.
