Pending analysis
Type:
CWE-787 Out-of-bounds Write
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfilter: ipset: add the missing IP_SET_HASH_WITH_NET0 macro for ip_set_hash_netportnet.c<br /> <br /> The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can<br /> lead to the use of wrong `CIDR_POS(c)` for calculating array offsets,<br /> which can lead to integer underflow. As a result, it leads to slab<br /> out-of-bound access.<br /> This patch adds back the IP_SET_HASH_WITH_NET0 macro to<br /> ip_set_hash_netportnet to address the issue.
