Vigil@nce - Linux kernel: use after free via inet_frag_lru_add

March 2014 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

An attacker can use a freed memory area in inet_frag_lru_add() of
the Linux kernel, in order to trigger a denial of service, and
possibly to execute code.

 Impacted products: Fedora, Linux
 Severity: 2/4
 Creation date: 04/03/2014

DESCRIPTION OF THE VULNERABILITY

IPv4 data can be fragmented in several fragments.

The inet_frag_intern() function manages these fragments. However,
the inet_frag_lru_add() function is called with an incorrect
locking sequence, so a memory area can be prematurely freed.

An attacker can therefore use a freed memory area in
inet_frag_lru_add() of the Linux kernel, in order to trigger a
denial of service, and possibly to execute code.
