Jon Howell reported a flaw in the Linux kernel's KVM (Kernel-based virtual machine) subsystem's handling of the XSAVE feature. On hosts, using qemu userspace, without the XSAVE feature an unprivileged local attacker could exploit this flaw to crash the system. (CVE-2012-4461) A flaw was discovered in the Linux kernel's 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)
