Canonical announced that a couple of vulnerabilities had been found in the Linux kernel packages, this time affecting the OMAP4 kernel of the Ubuntu 12.10 (Quantal Quetzal) operating system. The CVE-2012-4530 and CVE-2012-5532 Linux kernel vulnerabilities affected Ubuntu 12.10 (Quantal Quetzal) OMAP4.
According to Canonical, several security issues were fixed in the kernel. For example, it was 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 making hypervkvpd to exit.
