Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.5.2

Description The issue is caused by an integer overflow in the xt alloc table info function in net/netfilter/x tables.c of the Linux kernel. This can be exploited by a local attacker to gain privileges or cause a denial of service, resulting in heap memory corruption. The exploitation occurs via an IPT SO SET REPLACE setsockopt call.

Recommendations For Linux kernel versions prior to 4.5.2, update to a version 4.5.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the setsockopt call with the IPT SO SET REPLACE option to minimize the risk of exploitation.
