New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

A certain Red Hat patch to the __br_deliver function in net/bridge/br_forward.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging connectivity to a network interface that uses an Ethernet bridge device.
