A flaw was discovered in the Linux kernelβs handling of script execution when module loading is enabled. A local attacker could exploit this flaw to cause a leak of kernel stack contents.
(CVE-2012-4530)
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. (CVE-2012-5532)
