CVE-2012-0045

UnknownEPSS 1.01%

Last modified

CVE-2012-0045 is a vulnerability of currently unknown severity. The em_syscall function in arch/x86/kvm/emulate.c in the KVM implementation in the Linux kernel before 3.2.14 does not properly handle the 0f05 (aka syscall) opcode, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application, as demonstrated by an NASM file.. EPSS estimates a 1.01% chance of exploitation in the next 30 days.
