Linux kernel is vulnerable to authorization bypass attacks. This is due to disabled external interrupts in Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization (nVMX) feature enabled (nested=1). A local guest attacker could obtain read and write access to the hardware CR8 register causing an application crash.
