+Candidate: CVE-2009-1242
+Description:
+ The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX
+ implementation in the KVM subsystem in the Linux kernel before
+ 2.6.29.1 on the i386 platform allows guest OS users to cause a
+ denial of service (OOPS) by setting the EFER_LME (aka "Long mode
+ enable") bit in the Extended Feature Enable Register (EFER)
+ model-specific register, which is specific to the x86_64 platform.

+Candidate: CVE-2009-1243
+Description:
+ net/ipv4/udp.c in the Linux kernel before 2.6.29.1 performs an unlocking
+ step in certain incorrect circumstances, which allows local users to cause
+ a denial of service (panic) by reading zero bytes from the /proc/net/udp
+ file and unspecified other files, related to the "udp seq_file infrastructure."
