CVE-2012-5532
Published: 27 December 2012
The main function in tools/hv/hv_kvp_daemon.c in hypervkvpd, as distributed in the Linux kernel before 3.8-rc1, allows local users to cause a denial of service (daemon exit) via a crafted application that sends a Netlink message. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-2669.
From the Ubuntu security team
Florian Weimer discovered that hypervkvpd, which is distributed in the Linux kernel, was not correctly validating source addresses of netlink packets. An untrusted local user can cause a denial of service by causing hypervkvpd to exit.
