Description

The ip_frag_reasm function in net/ipv4/ip_fragment.c in the Linux kernel 2.6.32-rc8, and 2.6.29 and later versions before 2.6.32, calls IP_INC_STATS_BH with an incorrect argument, which allows remote attackers to cause a denial of service (NULL pointer dereference and hang) via long IP packets, possibly related to the ip_defrag function.

Affected products

Linux kernel: through 2.6.32; 2.6.28, 2.6.28-rc1, 2.6.28-rc2, 2.6.28-rc3, 2.6.28-rc4, 2.6.28-rc5 (+61)
