Description

This security bulletin contains information about 1 vulnerability.


1) NULL pointer dereference (CVE-ID: CVE-2014-3535)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel before 2.6.36 incorrectly uses macros for netdev_printk and its related logging implementation, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) by sending invalid packets to a VxLAN interface. A remote attacker can perform a denial of service (DoS) attack.
